In this steamy, suspenseful new novel from RITA Award–winning author Linnea Sinclair, a dangerously sexy space commander and an irresistibly earthy Florida police detective pair up to save the civilized galaxy . . . but can they save themselves from each other?

Bahia Vista homicide detective Theo Petrakos thought he’d seen it all. Then a mummified corpse and a room full of futuristic hardware sends Guardian Force commander Jorie Mikkalah into his life. Before the night’s through, he’s become her unofficial partner—and official prisoner—in a race to save the earth. And that’s only the start of his troubles.

Jorie’s mission is to stop a deadly infestation of biomechanical organisms from using Earth as its breeding ground. If she succeeds, she could save a world and win a captaincy. But she’ll need Theo’s help, even if their unlikely partnership does threaten to set off an intergalactic incident.

Because if she fails, she’ll lose not just a planet and a promotion, but a man who’s become far more important to her than she cares to admit.
