Riding Hard by J.L. Sheppard

Biker Dave “Dodge” Roth has never cared about his bad luck with women. He has other things to worry about—paying off debt his ex accumulated and most importantly, raising his three-year-old son, Cullen. When a new neighbor moves in, his boy makes it impossible to ignore her. Hard to miss, she’s beautiful, smart, sexy, perfect.
​
After her last failed relationship, kindergarten teacher Alexa “Lex” Millen has decided to do without men. She’s bought her first home in a small town in California and remodeled it to her liking. Naturally, she’s managed to move across the street from the world’s biggest jerk. His son’s adorable, but he won’t mind his own business. If only her engines didn’t rev every time he came around.
