Okay, to really get into this book, you’d better like puzzles, mysteries, and math (well, at least a little bit of math). Sophie, Rebecca, and Margaret are seventh-graders at an all-girls Catholic school in New York City. They’re into dances, music, and books. They’re just discovering that boys aren’t always gross and weird (just most of the time). They think this is going to be just another ordinary school year with breakfast at Perkatory and after-school homework sessions at Sophie’s apartment. But then, a lot of stuff happens. For one thing, there’s this new girl Leigh Ann, who looks like a Seventeen model. That’s pretty annoying, especially since the boy Sophie likes seems to get all silly and red whenever Leigh Ann is around. But the main action of the novel surrounds a ring — a really old, really valuable ring that is supposedly hidden somewhere in the church across from school. Soon, the girls are decoding secret messages, digging through moldy books in the library storeroom, breaking into to secret passageways, and hiding under tables from priests! This is definitely NOT your typical middle school mystery. If you read and liked The Puzzling World of Winston Breen, you might like The Red Blazer Girls, which also provides puzzles for readers to solve along the way. If only a fun, exciting mystery would drop into my lap in the middle of a boring Tuesday afternoon.
