Thunder by Danielle Pays

Lars
I was handcuffed and thrown into the ocean to die. As a former Navy SEAL, that was child’s play. The anger building in me is not.
When strange things begin to happen, I know my captors have returned. They threaten my tenant who happens to be a sassy brunette I can’t get off my mind.
I’ll do anything to keep her safe. Then I’ll find them, and they’ll regret ever crossing my path.

Madison
When my publishing company goes bankrupt taking all my income with it, my friend offers me a place to stay. Unfortunately, it comes with his grumpy but sexy brother, Lars, who keeps popping by to fix something.
My real problem starts the night a strange man digs up the backyard. When he doesn’t find what he’s looking for, he stalks me, convinced I’ll lead him to it. When I don’t, he makes it clear he’ll do whatever it takes to get it back.
Lars promises to protect me. I’m drawn to him in a way I can’t explain, and I worry it may be my heart that needs protecting.
