When Sara Donovan joins Project Enterprise she finds out that what doesn't kill her makes her stronger. An Air Force pilot - the best of the best to be assigned to this mission - Sara isn't afraid to travel far beyond the Milky Way on an assignment that takes her into a galaxy torn apart by a long and bitter warfare between the Dusan and the Gadi. After she's shot down and manages to land safely on an inhospitable planet, Sara encounters Kiernan Fyn - a seriously hot alien with a few secrets of his own - he's a member of a resistance group called the Ojemba, lead by the mysterious and ruthless Kalian. Together they must avoid capture, but can they avoid their growing attraction to each other? A mysterious, hidden city on the planet brings Sara closer to the answers she seeks - about her baffling abilities and her mother's past. She has no idea she's being pulled into the same danger her mother fled - the key to a secret left behind by a lost civilization, the Garradians. The Dusan and the Gadi want the key. So do the Ojemba. They think Sara has it. They are willing to do anything to get it. Sara will have to do anything to stop them.
