Ten-year-old Tae Kwon Do blue belt and budding rock hound Brendan Buckley keeps a "Confidential" notebook for his top-secret scientific discoveries. And he's found something totally top secret. The grandpa he's never met, who his mom refuses to talk about or see, is an expert mineral collector and lives nearby! Secretly, Brendan visits Ed DeBose, whose skin is pink, not brown like Brendan's, his dad's, or that of Grampa Clem's, who recently died. Brendan sets out to find the reason behind Ed's absence, but what he discovers can't be explained by science, and now he wishes he'd never found him at all. . . .From the Hardcover edition.
