The first book in a new series by the #1 bestselling author of the Thoughtless novels... Mackenzie Cox has a lot to prove. Daughter of a racing legend, she is eager to show the world that she has inherited her father's talent in the male-dominated sport of professional motorcycle racing. The last thing Kenzie needs is to be antagonized by her rival team's newest rider, Hayden Hayes. Plucked from the world of illegal street racing, Hayden immediately gets under Kenzie's skin. His insinuations that Kenzie is a spoiled princess who was handed her career fuels her desire to win, and much to her surprise, Kenzie soon learns she performs better when she's racing against Hayden. 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 always does her best to play by the rules, but when her team slips into a financial crisis, she has no choice but to turn to Hayden for help. The tension simmers during their secret, late-night rendezvous, but Kenzie has too much to lose to give in to her desires. Especially when she begins to doubt that Hayden has completely left his street life behind...

Feeling the rush comes with a price... Mackenzie Cox has lost everything—except Hayden Hayes. With Kenzie's racing career over, and her family no longer speaking to her, Hayden has been her rock, as she tries to pick up the pieces of what was once her life. But when Hayden's racing team hires his beautiful ex-girlfriend, Felicia, to be their new hotshot rider, Kenzie and Hayden's seemingly solid relationship begins to crack. Kenzie can only watch from the sidelines, as Felicia lives the life she was forced to leave behind, and as tension begins to build between Hayden and Kenzie, she wonders if Hayden isn’t the man she once knew.

Mackenzie Cox and Hayden Hayes are finally on solid ground again. But giving herself and her heart entirely over to Hayden still overwhelms Kenzie. Why can't she shake her fears and move forward with the man of her dreams? And how long will he wait until she can completely trust him again? And if the stress over her relationship isn’t enough, Kenzie also bears the weight of the success—or failure—of Cox Racing. No longer only focused on racing, she has to run the business side of things, which isn’t something she was prepared for, and she’s finding that she’s not even all that interested in it. So when she hires Dex Covington to take over during her mechanic’s maternity leave, and he arranges a meeting with his dad, a powerful businessman, capable of securing top sponsors for Cox Racing, it all seems too good to be true. And it is. With money running out, the future of Cox Racing is just as uncertain as when Kenzie’s father was at the helm. Does Kenzie have what it takes to save the business and be a top racer?
