No Life But This (UniCorp #2)

Rose spent most of her life asleep. Otto spent his as an object.

Rose Fitzroy woke from her long sleep to a changed world and new life. Her friend Otto watched her from afar, longing for what he felt he couldn't have. But just when things seem to be going right, his own biology backfires, sending him into a deathly spiral that neither of them can stop. His only hope lies on the distant ice moon of Europa, where an experimental treatment might bring him back from the brink.

But Europa is in a state of revolution, and Otto's brother Quin is tangled up in it. With Otto going slowly insane, and Rose haunted by ghosts of her old life, more than one world may soon be destroyed around them.
