Dinah Taylor has an orderly life that is just how she likes it. A perfectly furnished luxury apartment, a satisfying career as a scientist and CEO of her own company, and an uncomplicated personal life. But all of that changes when she meets seven-year-old Jonah.

The boy shows up one day, a scruffy dog by his side, in front of her office building. Dinah knows nothing about kids and even less about animals, but after she buys him breakfast, he shows up the next day...and the next. She tries to learn more about him, to help him, but he's remarkably skilled at evading her questions. And then, late one night, he calls her in a panic - his dog has been badly injured. Dinah rushes them to a local animal clinic, where she meets Garret, a veterinarian with a thriving practice and a passion for drawing. Though Jonah takes to Garret right away, for some reason neither understands, Dinah and Garret just don't mesh. But for Jonah's sake, their lives continue to collide, and slowly the relationship between these three strangers begins to change.
