Kat and the Totally Twisty Tunnels Time Forgot

When twelve-year-old aspiring archaeologist Kat Goldberg stumbles across dusty maps and journals suggesting her boring hometown is hiding an ancient tunnel system, she does the only reasonable thing: grabs a flashlight, a shovel, and sneaks out to investigate. But uncovering history is only half the battle. Between boy trouble, a menacing stranger, and an archenemy ready to unleash a totally social-life-destroying secret, Kat must also rely on Mateo-her loyal but easily terrified BFF, who still sleeps with the lights on and would rather be shopping at Sephora than exploring tunnels.
As danger, secrets, and middle school drama collide, Kat learns some discoveries come at a much higher cost than she ever imagined. Kat's seventh-grade year? Officially unhinged.
