Ride wild / Laura Kaye.

"Wild with grief over the death of his wife, Sam "Slider" Evans merely lives for his two sons. Nothing holds his interest anymore—not even riding his bike or his membership in the Raven Riders Motorcycle Club. But that all changes when he hires a new babysitter. Recently freed from a bad situation by the Ravens, Cora Campbell is determined to bury the past. When Slider offers her a nanny position, she accepts, needing the security and time to figure out what she wants from life. Cora adores his sweet boys, but never expected the red-hot attraction to their brooding, sexy father. If only he would notice her... Slider does see the beautiful, fun-loving woman he invited into his home. She makes him feel too much, and he both hates it and yearns for it. But when Cora witnesses something she shouldn’t have, the new lives they've only just discovered are threatened. Now Slider must claim—and protect—what's his before it's too late."
