The tree is beautiful and they call her Eden. Her branches reach for the stars. She is like all other trees on planet Earth save for her enormous size. Still, she has leaves and she has bark. She turns sunlight into life. But this tree does not sprout from the dirt. Eden fills the sky, high in orbit above the blue expanse of Uranus. Eden changes humanity's very concept of extraterrestrial life. Dr. Malcolm Green is sent to Eden to audit a science team studying this extraordinary tree from the dark confines of space station Lola. But with unexplainable accidents plaguing the team, tensions are mounting between scientists and custodial staff. Is there a future for this project and Lola? Only Malcolm Green can make that call. From the second he sets foot on Lola, Malcolm's own future is in jeopardy. He soon finds that love, friendship, and his own mortality tremble like a leaf at the sound of Eden's call.
