The Monster Hunters Club
Every reader who joins becomes a Monster Hunter — collecting stickers (starting with a free printable sticker sheet), spotting monsters at real racetracks around the world, just like Enzo and Leni do in the books.
What is the Monster Hunters Club?
In every Track Monsters book, the same two kids show up: Enzo, who sees the story; and his sister Leni, who checks the math. Together with their Grandpa Vito — a retired weekend racer who's driven these tracks more times than he can count — they go back and discover the wonder hiding in plain sight.
The Monster Hunters Club is the real-world version of that adventure. Members collect character stickers and spec stickers from each book in the series, keeping track of every monster they've spotted at real racetracks from California to Germany, Monaco to the biggest ovals in America.
It's free. It's for readers of all ages. And the only requirement is curiosity.
