In one day, four lives weave together in unexpected ways. Virgil Salinas. Valencia Somerset. Kaori Tanaka. Chet Bullens. They aren't friends - at least not until Chet pulls a prank that traps Virgil and his pet guinea pig at the bottom of a well. This disaster leads Kaori, Gen, and Valencia on an epic quest to find the missing Virgil. Is it a coincidence that their lives collide? Or are some things just meant to be? 10+ Winner of the 2018 Newbery Medal.
