Corrupted Lies by Jane Blythe

Sparks fly between two friends when they become the target of a firebug.

What was supposed to be a couple of hours hanging out with her best friend turns into a nightmare for Alannah Johansen when they’re trapped in the burning basement of the gym she owns. Surviving only thanks to his quick thinking that’s nowhere close to the end of things. Fires keep popping up everywhere she goes until she’s got no choice but to try to disappear if she wants to stay alive.

When Jake Holloway was six years old he made a promise to Alannah, no one would hurt her again. Now almost thirty years later he’s trying to honor that vow by keeping his distance as people continue to hunt his family. One moment of weakness puts her in the crosshairs and now he’s going to have to fight with everything he has if he doesn’t want to lose her forever.

But as they fight for their lives things between them begin to change and he realises death might not be the only reason he could lose his best friend.
