Dr. Lucy Peterman was not built for a messy life. A well-respected surgeon whose patients rely on her warmth, compassion, and fierce support, Lucy has always worked hard and trusted in the system. She's not the sort of person who ends up in a twelve-step program after being caught stealing supplies from her hospital.

But that was Lucy before the accident—before her husband and unborn baby were ripped away from her in an instant, before her future felt like a broken promise. Caught red-handed in a senseless act that kept her demons at bay, she's faced with a choice: get some help or lose her medical license.

Now she's reluctantly sharing her deepest fears with a bunch of strangers, avoiding her loneliness by befriending a troubled girl, pinning her hopes on her husband's last gift, and getting involved with a rugged cop from her past. It's only when she is adopted by a stray mutt and moves her group to the dog park that she begins to truly bond with the ragtag dog-loving addicts—and discovers that a chaotic, unplanned life might be the sweetest of all.
