Featuring Girls In STEM, a missing best friend, and the intrigue of geocaching, FIRST TO FIND is a high stakes adventure where kids are the heroes of their own stories. Everyone assumes that 12yo Caitlin Mallory's best friend Maisy Sutton drowned in the American River on Memorial Day weekend. But when Cait and her other best friend Lio find Maisy's favorite bracelet in a geocache, they know Maisy might still be alive. As Cait and Lio search the woods along the river, new geocaches appear that contain more treasures connected to Maisy, and new friends shed light on possible suspects in Maisy's disappearance. Working together, the friends hunt down the geocaches before other catchers intercept the clues, extinguishing the trail, and the hopes of finding Maisy, forever.
