When your life has a deadline, why play it safe? Grav-walker Jasper Pine has always known she’d die young. She makes a living hunting for salvage in the decaying, three-dimensional maze of the gravity zones, where any direction can be down and every leap could be your last. Even if her reckless lifestyle doesn’t kill her, the alien infection inside her will soon explode, and the resulting cataclysm of broken gravity could endanger the entire planet. She’ll die to prevent that from happening. Then an unexpected glimmer of hope appears and changes everything. A feral boy holds the key to her future, but he’s been captured by a ruthless militarized cult. Jasper will have to turn to the one person she should be avoiding, Ryan Latrans, a charming outsider who’s been sent into the zones to retrieve a sample of the alien infection for a powerful and unscrupulous man. With millions of lives at stake and time running out, can Jasper afford a leap of faith?
