It's Plum' Lovin from my favorite Janet Evanovich. It's a Stephanie Plum between-the-numbers novel.
And it started with this:
Men are like shoes. Some fit better than others.And sometimes, you to out to shopping and there's nothing you like. And then, as luck would have it, the next week you find two that are perfect, but you don't have the money to buy both.I really like quotes from Stephanie Plum novels :)
