The Baseball Card Adventure series is a rare breed: it's educational without being preachy and exciting without being mindless. Dan Gutman knows his audience—middle-grade kids who want fast-paced action and a relatable protagonist.

Stosh isn't a perfect hero; he's a kid with a weird power trying to navigate both the 1920s and his own modern-day family issues. The 2020 box set is a massive value for parents looking to keep a kid reading for months. It’s a solid, high-quality recommendation that holds up even as sports culture changes.
