Seeing Red — Jill Shalvis

Summer Abrams nearly died trying to save her father from a warehouse fire that, in the end, took his life. Consumed by guilt, she never set foot back in the town where her world fell apart. But now, twelve years later, another fire has ripped through that very warehouse, drawing Summer back to Ocean Beach--and to the man who was once her best friend...and is now a wildly sexy fire marshal who ignites her deepest desires.

Walker Montana has spent most of his life keeping people at bay. Summer was the only person he'd ever let in, but she'd broken his heart--and then took off without a word. After all these years, she's back--and she won't leave until they track down the arsonist responsible for this latest fire. Now Walker, who swore he'd never fall for Summer again, discovers he can't resist the scorching heat between them--and suddenly he's wondering if all these hot nights could be become something more lasting...
