From the acclaimed author of Extraordinary Birds, a powerful story about family, friendship, and the light that can be found even in the darkest of places.

Cassie's always looked up to her mom, a vibrant woman bursting with grand ideas. Together they planned to check off every dream on their think-big bucket list, no matter how far the adventures took them. The future seemed unlimited.

But then came the diagnosis, and Mom started to lose her memories. Even the ones Cassie thought she'd never forget. Even Cassie's name.

Cassie tries her hardest to keep Mom happy . . . to focus on math lessons and come up with art ideas that used to burst off her pen. But as Mom's memories dimmed, so did Cassie's inspiration. She's even pushed away Bailey, the one friend who could help make things okay.

So, Cassie decides to take action. It's time for one last adventure… even if it means taking a big risk to get there.
