Told in two voices, Lou Patterson reconnects with her neighbor and ex-best friend Sam Alvarez, now seniors in high school, after they rediscover their childhood bucket list.

Luisa (Lou) Patterson grew up across the street from Sam Alvarez in the small, quirky town of Port Coral. Then middle school-- and an most embarrassing serenade-- happened, and Lou and Sam haven't talked in four years. Now it's the summer before their senior year. Lou is retaking her SATs, signing up for way too many AP classes. When she finds the bucket list she and Sam wrote together as kids, before Sam's father was diagnosed with cancer, she's shocked to see that she hasn't accomplished any of the goals she'd set for herself. Lou sets out to finish the list, and Sam decides to tag along. Sam and Lou might just be able to find a way through the future, and also a way back to each other. -- adapted from jacket
