Burning Secrets by Susan May Warren

RESCUE. DANGER. DEVOTION.
THIS TIME, THEIR HEARTS ARE ON THE LINE.

Wrong place, wrong time…
Wildlife biologist JoJo Butcher isn’t just a smokejumper for the Midnight Sun crew—she’s also in Alaska to finish up her wolf research…until, oops, she finds herself face-to-face with a wolf with nowhere to go…
And then she’s rescued by a hero from the woods. Who exactly is he, and what secrets is he hiding?

He’s living a double life…
Undercover FBI informant Michael Crew Sterling hates his life. Buried deep inside a domestic terrorist group, he’s in over his head, trying to discover their lethal plans. And then he saves the life of JoJo Butcher, and suddenly she is sunshine to his dark soul…
Until she accidentally walks into nightmare.

Now Crew must keep her alive by proving that she’s his girlfriend. And she has to play along, or they’ll both be killed. And when they discover what the group is really doing, Crew will have to make a choice that could cost him everything he’s sacrificed to save the woman he’s falling for.
