WHY THIS BOOK

Most kids’ books entertain… or they teach. This one does both.

The Museum’s Secret Alphabet is a language arts mystery book for kids where the lessons are how the case gets solved, not a lecture tacked onto the end. Your child learns where our alphabet came from, how Greek and Latin roots build English words, and why spelling is so tricky, while helping crack a hundred-year-old code.

The story

A little brown notebook from the old courthouse attic has gone on display at the Heritage Hollow Museum, its pages covered in loops, hooks and dashes. Even experts from the city can’t read a word of it.

Slick and Muffin team up with Nora, a spelling-bee champion, and Felix, who can’t spell to save his life but hears words better than anyone. Their clues lead from a glass case to a library basement.
