Let’s Get Physical by Cassie Cross

Corinna McKnight is a chronically single girl in need of toned abs and a hot date for a wedding that her highly successful, deliriously happy lifelong frenemy will be attending. The wedding is only six weeks away and she doesn’t have much time to make it look like she has her life together. Luckily, her best friend’s boyfriend owns the hottest gym in town and sets her up with Noah, the best personal trainer he has on staff.
Noah Cutter is at a pretty good place in his life. He has a job and he loves working for his best friend, Hunter. Noah is in high demand, mostly for his talent, but sometimes for his body and Hunter has one very firm rule: no fooling around with the clients.
It’s an easy rule to follow until he meets Corinna, who makes him want more out of life and leaves him straddling the line between breaking a promise and betraying his heart.
