The Break-up (Full Hearts #5)
M.J. Summers

Wes Young spent more than twenty years in the Marines and the past two years in protection services. The only thing he protects more carefully than his clients is his heart. When he takes on the task of guarding Courtney Bennett, the last thing he wants to do is spend his days and nights with a spoiled, self-involved actress. Before long, Wes realizes that she is not at all what he thought. For the first time in his life, he finds himself navigating the minefield of love, trying to avoid a broken heart.
Will they risk it all to be together or return to the lives they knew before The Break Up?
