Showing Someone Like You by Susan Mallery

It turns out her childhood crush, Mac Kendrick, a burned-out LAPD cop, has also come back to sleepy Los Lobos. Even though Mac rejected her back in high school, Jill can't deny the attraction she still feels for him. Now Jill and Mac are tangled in enough drama to satisfy the most jaded L. A. denizens—Mafia dons, social workers, angry exes and one very quirky eight-year-old make even the simplest romance complicated.

And it all goes to prove that when it comes to affairs of the heart, there's no place like home. An unlikely pair. . . but a perfect match.
