Dangerous Rush by S. C. Stephens

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.
