See You Smile by Bijou Hunter

Nevaeh Majors isn’t looking for love, especially with a recently released biker, dad of two, and man twice her age. She isn’t mom material, and relationships haven’t proven to be her strong suit. Once she gets one look at Handsome Sam and goes gaga, Nevaeh can’t walk away.
Samson “Handsome Sam” Donner is freshly released into a world he doesn’t recognize anymore. His two kids have gotten big while he was away. The Reapers Motorcycle Club is under new management. There’s even a new clubhouse run by the sexiest woman he’s ever seen.
Neither Nevaeh nor Sam wants a relationship. The timing’s bad, and they’re ill-suited for each other in a whole bunch of ways. But sometimes, there’s no denying what the heart needs.
