Theodore Finch is fascinated by death, and he constantly thinks of ways he might kill himself. But each time, something good, no matter how small, stops him. Violet Markey lives for the future, counting the days until graduation, when she can escape her Indiana town and her aching grief and guilt in the wake of her sister's recent death. When Finch and Violet meet on the ledge of the belltower at school, it's unclear who saves whom. And when they pair up on a project to discover the "natural wonders" of their state, both Finch and Violet make more important discoveries: It's only with Violet that Finch can be himself -- a weird, funny, live-out-loud guy who's not such a freak after all. And it's only with Finch that Violet can forget to count away the days and start living them. But as Violet's world grows, Finch's begins to shrink.
