3.5-4 stars 
 Mackenzie Cox has a legacy to carry on. Her father was a successful motorcycle racer, from his rookie season, and now it falls to her to save the racing team he runs. 
 Hayden Hayes has his own reasons for racing, though his start was far less prestigious as Mackenzie's. His history follows him to the professional circuit as rumors and suspicion. 
 Mackenzie is driven to succeed, but fearful of letting go, fearful of failure. She feels pressure to save the family company single-handedly and is determined to make her father proud of her. Racing is her life. 
 The chemistry between Hayden and Mackenzie crackled from the beginning. But at times it felt like the chemistry was more about competition than attraction. As the book progressed, the competition lessened, but initially I had a hard time believing these two were as fiery as they said things felt. 
 The drama of the feud between the Cox and Benneti race teams often overshadowed the chemistry between Mackenzie and Hayden. At times it felt almost Romeo and Juliet in it's intensity, but it also felt arbitrary because of the situation. These two are forbidden contact simply because of the race teams they work for, forget the fact that both their times begin improving when they train together. The hatred between the two older men who ran the companies even broke things between father and daughter. 
 This was a fast paced read full of drama and action as Hayden and Mackenzie snuck around behind the backs of their teams and families. The side characters add to the tension between the main characters as they feed into the feud just as strongly as the founding fathers. I look forward to more from these characters, particularly Mackenzie's friends Nikki and Myles. 
 The ending feels ambiguous though. With a final twist, Mackezie and Hayden's story doesn't feel like it's over, like there are more challenges they need to face before their relationship is settled, though the book is not listed as part of a series. I want to find out what happens next for them, but am also a little unsettled not knowing if this really is the end of their story or if there will be a second book for these two. 
 I was gifted a copy in exchange for an honest review.
