Noah Baker never wanted to betray The Others. But if his military commanders want him to covertly investigate a Lupine scientist—whose extraordinary research on sensory perception in werewolves could be used to develop werewolf-sharp senses in human soldiers—Noah must oblige. Even if it means deceiving the woman he desires the most.

Samantha Carstairs is the personal assistant to the Alpha of the Silverback Clan, and as best friend to the Lupine community's most brilliant scientist, she is privy to its most dangerous secret. Noah knows that Sam will never leak the scientific research…so he must find another way to get it, while keeping Sam close. But someone else is after Sam's secret. Who is the other spy infiltrating The Others? If their genetic secrets get into the wrong hands, all hell could break loose. Now Noah's true loyalty is put to the test as he fights to protect The Others—and his beloved Sam—and find the imposter…before it's too late.
