One In Vermillion by Jennifer Crusie

From the Bestselling duo that wrote Agnes and the Hitman, the third book in a new series.

Liz Danger is stuck in her hometown of Burney, Ohio, because her insane employer has rented a house there for the summer, which means she has three more months of trying to get a copy edit done, babysitting a seven-year-old, and figuring out what to do with three hundred and ninety-two teddy bears. And then there’s her mother. Even the good news that she’s living with a hot cop is tempered by the knowledge that sooner or later, she’s going to have to figure out her future, and she’s still not sure what she wants that to be.
Vince Cooper is stuck in a town that keeps asking him when he’s going to make an honest woman of Liz Danger and in a job that’s just sunk into anarchy because of local and state politics that are kneecapping the police department, not to mention a biker gang and Liz’s ex-boyfriend who still hasn’t figured out that the ex part is permanent. Good thing he has Liz to come home to . . . until he doesn’t.
As Liz and Vince try to navigate their increasingly complicated relationship, they’re finding out startling new things about themselves and the town they’re trying to protect, and that means dealing with greedy politicians, arson, broken hearts (not theirs), vandalism, questionable real estate, murder, and a lot of soggy bears.
