The Rule Book (original) Sarah Adams

Nora Mackenzie’s entire career lies in the hands of famous NFL tight end Derek Pender, who happens to be her extremely hot college ex-boyfriend. Nora didn’t end things as gracefully as she could have back then, and now it has come back to haunt her. Derek is her first client as an official full-time sports agent, and he’s holding a grudge.

Derek has set his sights on a little friendly revenge. If Nora Mackenzie, the first girl to ever break his heart, wants to be his agent, oh, he’ll let her be his agent. The plan is simple: make Nora’s life absolutely miserable. But if Derek knows anything about the woman he once loved—she won’t quit easily.
