main trunk. Alice, surrounded by pedals, cranks, levers, and pulleys, was seated on a bench built into the wood. She spun one of the cranks, and the tree straightened again. Then she grabbed the front of Gavin’s shirt and pulled him down for a long kiss.
The world stopped for a moment. The pain in Gavin’s body receded, and Alice’s warm lips pressing against his own made him feel both safe and calm, even as they stole his very breath. He kissed her back, so thankful to see her that tears came to his eyes. They parted.
“That’s for being alive when I came to get you,” Alice said, then slapped him lightly on the cheek. “And that’s for getting captured and scaring me half to death in the first place.”
“I love you, too.” Gavin said. “Now, run! He’ll recover in a minute, and I’m not up for fighting him. I don’t suppose you brought Dr. Clef’s power gun.”
“Too heavy to carry down the rope, darling.” Alice held out an arm and whistled. The whirligig buzzed in and settled on her shoulder. Click took up a position on the bench beside her. “We’re safe for the moment anyway. These trees don’t move unless you tell them to. Do you want to drive? I never handled the original Tree back home.”
Below, Antoine had already regained his feet and was staggering toward the worktable.
“Antoine can control them from the ground,” Gavin said tersely. “Go! Go now!”
Alice didn’t hesitate or ask for further explanation, which was one of the many reasons Gavin loved her. She hauled ropes and yanked levers. The tree stomped forward on a bifurcated trunk that ended in balled roots. Antoine reached the worktable—and the control panel. Alice stomped another step forward, and another. She had nearly cleared the ring of mutated trees.
“Will I kill them?” Antoine screamed from the control panel. “Will I?”
“He’s losing his mind,” Gavin observed as Alice worked. “He’s not even answering his own questions.”
Antoine’s hands moved swiftly over the panel, flipping levers and twisting dials. A low-pitched hum throbbed through the earth and vibrated even the tree.
“Is that French for
“Yes,” Alice said. “He must like the vibrations. I find them most uncomfortable.”
“It’s a very low C,” said Gavin.
“You and your perfect pitch. Good heavens, how I missed you, darling.”
Antoine yanked a large lever, and all the other trees snapped to attention. “Destroy them!”
“Uh-oh,” Gavin said. “Can you move faster?”
“The tree is trying to follow Antoine’s orders instead of mine,” Alice replied grimly. “But I seem to be getting the hang of it.”
The tree picked up speed even as the other trees—four of them—turned as one and stomped in Alice’s wake. Alice, for her part, was guiding their own tree straight toward the perimeter of the glassy greenhouse. Gavin clung to the branch with white fingers. The noise was incredible. Heavy trees thudded across the ground like an army of gods, the vibrations that controlled the others throbbed in Gavin’s bones, and Antoine’s shrieks chased them faster than a flock of ravens.
“It’s still fighting me,” Alice shouted. Her arms and legs worked the controls in a blur. “It wants to do what the others are doing.”
“How are we going to get out of here?” Gavin called over the noise. “I don’t see a door.”
“Cover your eyes!” was all Alice said.
They hit the greenhouse wall. Glass exploded in a thousand directions, and Gavin lurched forward. His feet left the branch, and he was flying through the air. The tree hadn’t smashed completely through, and its top third was caught on the remains of the greenhouse. Gavin tumbled forward, but the clockwork plague suddenly took over. The universe slowed. Green leaves and glittering glass surrounded him like strange snowflakes. Just below him were the tree’s branches, and he was aware of the drag coefficient of the bark, which places would slow him down and by how much. He saw every bump and nub, every side branch and twig, and his brain instantly mapped out a route that would take him to safety. Behind him floated Alice, and he calculated the arc of her flight pattern as well, then readjusted his own route accordingly.
The universe burst back into motion, and his body, finally free of its earlier stiffness, turned the dive into controlled leaps and jumps down the tree’s branches until he came to rest on solid ground outside the greenhouse exactly where he wanted. Then he whirled and caught Alice. Her helmet flew on without her and cracked against a boulder. Gavin nearly went over backward, but just managed to keep his feet with Alice in his arms. Thank God. He held her tight, feeling her heart pound against his chest. The universe could come to a complete stop now, and he wouldn’t mind in the slightest.
“Thank you, kind sir,” she gasped, pushing a lock of tousled honey-brown hair out of dark brown eyes. “That quite took my breath away.”
“Clockwork reflexes,” Gavin said. “I should be in a circus.”
The tree was now standing with its lower branches sticking out of the glittering greenhouse, while the upper part was still trapped inside. Behind it stampeded the other trees. Click trotted out of the wreckage, his metal ears back, and the whirligig whizzed overhead, unhurt.
“Now what?” Gavin asked, setting Alice down. “You do have a plan, right?”
She took his hand. “Yes: run!”
A rutted dirt road twisted through the woods ahead of them, and they sprinted down it. The late-summer breeze should have been uncomfortably warm, but it felt refreshing after the hot, still air of the greenhouse. Behind them, glass smashed and tinkled as the trees hit the side of the greenhouse, but they were tangling up with one
