The Rebound Girl by Tamara Morgan

Plastic surgeon Whitney Vidra knows all about getting over a cheating ex. She followed her boyfriend halfway around the world before she found out about his infidelity. Now she’s focusing on her career and her friends, and using men just for single-serving, no-strings fun. Until she meets charming Matt Fuller.
Newly single Matt is captivated by the vibrant Whitney, in every way the opposite of his cheating ex-wife. When he confesses to Whitney that he hasn’t had sex since his divorce, she volunteers to be his rebound girl. But Matt’s not a no-commitment kind of guy—he’s either all in, or all out.

Whitney is determined to remain attachment-free, but Matt is equally determined to prove to her that what they have is more than just a rebound fling.
