As she stood there, a troubling thought refused to leave her mind, no matter how much she tried to push it away. An absurd line of reasoning, but all day long it had been percolating. What if my own abilities could be equivalent to those of a Kwisatz Haderach? I already have a natural ability to control the great worms. I have the Atreides genes, and centuries of the Sisterhood's perfected knowledge to draw upon. Would I dare?

She felt voices surfacing from within; one rose above the others. The ancient Reverend Mother Gaius Helen Mohiam, repeating something that she once said so long ago to a young Paul Atreides: "Yet, there's a place where no Truthsayer can see. We are repelled by it, terrorized. It is said a man will come one day and find in the gift of the drug his inward eye. He will look where we cannot--into both feminine and masculine pasts . . . the one who can be many places at once . . ." The old crone's voice drifted away, without giving Sheeana any advice, one way or the other.

With a sneer, the Rabbi interrupted her thoughts. "And you trust that old Tleilaxu to help you, when he's desperate to achieve his own goals before dying? Scytale hid those cells for so many years. How many of them contain dangerous secrets? You've already discovered Face Dancer cells among the samples. How many of your ghola abominations are traps laid by the Tleilaxu?"

She gazed at him dispassionately, knowing that no argument would ever sway him. The Rabbi made the sign of the evil eye, and fled.

DUNCAN ENCOUNTERED SHEEANA in an empty corridor, in the dimness of the artificial night. The no-ship's recyclers and life-support systems kept the air comfortably cool, but upon seeing her alone like this Duncan felt a flush of heat.

Sheeana's large eyes fixed on him like a weapon's targeting system. Feeling a tingle like static electricity on his skin, he cursed his body for being so easily tempted. Even now, three years after Sheeana had broken the debilitating chains of Murbella's love, the two of them still found themselves drawn irresistibly into unexpected bouts of sex as frenetic as any he and Murbella had ever shared.

Duncan preferred to manage the circumstances of their casual meetings, always trying to make certain that others were present, that he had safe guardrails to prevent him from falling off a dangerous cliff. He did not like to be out of control: That had already happened too many times.

He and Sheeana had surrendered to each other like terrified people huddling in a bombed-out battle zone. She had cauterized him to cure his debility and stolen him from Murbella, yet he felt like a casualty of war.

Now as he saw Sheeana's expression flicker, Duncan thought she felt the same sense of vertigo and disorientation. She tried to sound reserved and rational. "It is better if we don't do this. We have too many concerns, too many risks. Another regenerator system has just failed. The saboteur--"

"You're right. We should not." His voice was hoarse, but they had already started down a path with ever-increasing consequences. Duncan took a hesitant step forward. The muted corridor lights reflected off the no-ship's metal walls. "We shouldn't do this," he said again.

Desire swept like a wave over both of them. As a Mentat he could observe and assess, concluding that what they were doing was simply a reaffirmation of humanity. When they touched fingertips, lips, and skin, both of them were lost. . . .

Later, they rested on tangled sheets in Sheeana's quarters. The air carried a moist muskiness. Duncan lay sated with his fingers laced in his wiry dark hair. He was confused and disappointed in himself. "You've taken away too much of my control."

Sheeana raised her eyebrows in the dim light, showing amusement. Her breath was warm and close to his ear. "Oh? And Murbella did not?" When Duncan turned away and did not answer, she chuckled. "You're feeling guilty! You think you've betrayed her somehow. But how many female imprinters did you train back on Chapterhouse?"

He answered the question in his own way. "Murbella and I were trapped together, and no part of our relationship was voluntary. We had a mutual addiction, two people brought to a stalemate. That isn't love or tenderness. For Murbella--for all of you witches--our love-making was supposed to be 'just business.' But I still had feelings for her, dammit! It isn't a matter of whether or not I should.

"But you--you were like a violent detoxification of my system. The Agony served the same purpose for Murbella, breaking her bond to me." He reached out and cupped Sheeana's chin. "This cannot happen again."

Now she looked even more amused. "I agree that it should not . . . but it will anyway."

"You're a loaded weapon, a full Bene Gesserit. Every time we make love, you could easily let yourself get pregnant. Isn't that what the Sisterhood would demand? You could carry my child whenever you allow yourself to do so."

"True. But I haven't. We are far from Chapterhouse, and I make my own decisions now." Sheeana pulled him back to her.

Scientists see sandworms as specimens, while the Fremen see them as their god. But the worms devour anyone who tries to gather information. How am I supposed to work under such conditions?

--IMPERIAL PLANETOLOGIST PARDOT KYNES,

ancient records

Sheeana stood in the high observation gallery where she and Garimi had once gone to discuss the future of their journey. The kilometer-long great hold was large enough to offer the illusion of freedom, though much too small for a brood of sandworms. The seven creatures were growing but remained stunted, waiting for the promised arid land. They had been waiting a long time, perhaps too long.

More than two decades ago, Sheeana had brought the small worms aboard the no-ship, stealing them from the growing desert band on Chapterhouse. She had always intended to transplant them to another world, far from the Honored Matres and safe from the Enemy. For years, the worms had zigzagged endlessly in the sand-filled confines of the hold, as lost as everyone else on the Ithaca. . . .

She wondered if the no-ship would ever find a planet where they could stop, where the Sisters could establish a new and orthodox Chapterhouse, rather than the mongrel organization that made concessions to the ways of the Honored Matres. If the ship simply fled for generations and generations, it would be impossible to find a perfect world for the sandworms, for Garimi and her conservative Bene Gesserits, for the Rabbi and his Jews.

She recalled searching Other Memory for advice the evening before. For a while, there had been no response. Then Serena Butler, the ancient leader of the Jihad, came to her just as Sheeana drifted off to sleep in her quarters. Long-dead Serena told of her experiences being lost and overwhelmed by an endless war, forced to guide vast populations when she herself didn't know where to go.

"But you found your way, Serena. You did what you had to do. You did what humanity needed."

And so will you, Sheeana.

Now, seeing the sandworms ripple the sand far below, Sheeana could sense their feelings in an indefinable way, and they could sense hers. Did they dream of endless, dry dunes in which to stake their territory? The largest of the worms, nearly forty meters long with a maw large enough to swallow three people abreast, was clearly dominant. Sheeana had given that one a name: Monarch.

The seven worms pointed their eyeless faces toward her, displaying crystalline teeth. The smaller ones burrowed into the shallow sand, leaving only Monarch, who seemed to be summoning Sheeana. She stared at the dominant worm, trying to understand what it wanted. The connection between them began to burn inside her, calling her.

Sheeana descended to the sand-filled cargo hold. Stepping out onto churned dunes, she strode directly toward the worm, unafraid. She had faced the creatures many times before and had nothing to fear from this one.

Monarch towered over her. Putting her hands on her hips, Sheeana looked up, and waited. In the heady days on Rakis, she had learned to dance on the sands and control the behemoths, but she had always known she could do more. When she was ready.

The worm seemed to be playing upon her need for understanding. She was the girl who could communicate with the beasts, who could control and understand them. And now, in order to see her own

future, she had to go farther. Literally and metaphorically. It was what Monarch wanted. Dangerous and frightening, the creature exhaled a stink of inner furnaces and pure melange.

"So, now what do we do, you and I? Are you Shaitan, or just an impostor?"

The restless worm seemed to know exactly what she had in mind. Instead of rolling its body toward her so she could climb its rings to ride, Monarch faced her with its round maw open. Each milky-white tooth in a mouth the size of a cave opening was long enough to be used as a crysknife. Sheeana did not tremble.

The sandworm laid its head on the soft dunes directly in front of her. Tempting her to a symbolic journey, like Jonah and the whale? Sheeana wrestled with her fears, but knew what she must do--not as a charlatan's performance, for she doubted anyone was watching her, but because it was necessary for her own understanding.

Monarch lay waiting for her, mouth agape. The worm itself became a secret doorway, luring her like a dangerous lover. Sheeana stepped past the portcullis of crysknife teeth and knelt inside the gullet, inhaling the rank cinnamon odor. Dizzy and nauseated, she could barely breathe. The sandworm did not move. Willingly, she worked her way deeper inside, offering herself, though convinced that her sacrifice would not be accepted. It wasn't what the worm wanted from her.

Without looking back, she crawled farther down the throat into dry, dark warmth. Monarch did not twitch. Sheeana kept going, felt her breathing slow. Deeper and deeper she went, and soon guessed that she had gone at least half the length of the prone worm. Without the friction heat sparked by roaming endless deserts, the worm's gullet was no longer a furnace. Her eyes became accustomed to what she realized was not total darkness, but was instead an eerie illumination that seemed more the product of another sense in her own mind than traditional eyesight. She could dimly see the rough, membranous surface around her, and as she proceeded, the undigested odor of melange precursors grew stronger, more concentrated.

Finally she reached a fleshy chamber that might have been Monarch's stomach, but without digestive acids. How did the captive sandworms survive? The odor of spice was more intense here than she had ever experienced--so much so that an ordinary person would have suffocated.
