Book excerpt: From the acclaimed author of The Great Shelby Holmes comes a new middle grade story about two summers-three decades apart-and the box of secrets linking them together. This is going to be the worst summer ever for Peyton. Her family just moved, and she had to leave her best friend behind. She's lonely. She's bored. Until . . . she comes across a box buried in her backyard, with a message: I'm so sorry. Please forgive me. Things are about to get interesting. Back in 1989, it's going to be the best summer ever for Melissa and Jessica. They have two whole months to goof around and explore, and they're even going to bury a time capsule! But when one girl's family secret starts to unravel, it's clear things may not go exactly as planned. In alternating chapters, from Peyton in present day to Melissa three decades earlier (a time with no cell phones, no social media, and camera film that took days to develop, but also a whole lot of freedom), beloved author Elizabeth Eulberg tells the story of a mystery that two sets of memorable characters will never forget.
