Spaceship captain Tara Rowan has her secrets. One is her Rider, Zie—an organic symbiote, like a living tattoo—that enhances Tara's physical abilities. But Zie is no ordinary Rider, and Tara can never risk anyone discovering Zie's true origins. Especially not the sexily dangerous stranger who appears out of nowhere and makes Tara's pulse race...

Except that “Trace Munroe” isn't exactly who he says he is. He's in fact a Holy Knight, who does everything by the book, and Tara is his only lead in tracking down a kidnapped princess. And Trace will do whatever it takes to get that information—including blackmail. But a blazing attraction to Tara is definitely complicating things...especially when Trace realizes that following his code of honor means destroying the woman he's falling for.
