For Mackenzie Cox, racing motorcycles is in her blood. Born into a family legacy, she's determined to show the world that she has inherited her father's talent in this male-dominated sport. The last thing Kenzie needs is to be antagonised by her rival team's newest rider, Hayden Hayes. Hayden, exceedingly arrogant and outrageously attractive, immediately gets under Kenzie's skin and she can't help but be distracted.As Kenzie and Hayden push each other on the track, the electric energy between them off the track shifts into an intense - and strictly forbidden - attraction. The only rule between their two ultra-competitive teams is zero contact. Kenzie needs a win, and she also needs to stay away from Hayden. Unfortunately for her though, one thing has become all too clear: she can't.Fuelled by passion, driven by desire, Hayden and Mackenzie both want to win more than anything else. Except for, maybe, each other. But anger, jealousy and extreme competitiveness aren't their only obstacles . . .
