Ryker by Rhian Blaque

He likes rules and order — she likes fun and games.
What do you get when you mix one part sass and two parts strict? A matchmade in heaven.
Ryker is her older brother’s best friend, but he’s also the firefighter working the case of intentional arson. Oops. Corinne only started the fire to ensure that her roommate has the chance to ask out Ryker’s partner, but everything falls apart when he gets up the courage to ask her out instead.
When he threatens to turn her over his knee for a good ol’ fashion spanking, Corinne’s heart flips over. Who’s this man with all his muscles and why is he suddenly making her feel all these things? It should be criminal.
