Unforeseen Riot by Karen Renee

Mallory Pierce has been hiding from life after losing her husband and son to a drunk driving accident more than a year ago. Friends tried to help Mallory get back into the swing of things; but it isn’t until she meets Riot MC biker, Cal Robertson, that Mallory begins to live again. The chemistry between Mallory and Cal is explosive from the beginning, and when Cal offers her a ride on his motorcycle, Mallory cannot refuse.

Cal is fascinated by the spunky brunette, who seems to know how to push all his buttons. Things go awry when a situation requires him to bring her to his club. Despite their rocky start, the pair cannot stay away from one another. His protective instincts kick into overdrive when a member of a rival motorcycle club shows a dangerous interest in Mallory. Cal can no longer deny his feelings for her, and the more he finds out about her, the more he wants Mallory in his life.

Permanently.
