Winner of the 2018 Lee & Low/Tu Books New Visions Award, Julieta and the Diamond Enigma is a fun whodunit with a smart heroine who has a penchant for finding trouble. Julieta is the nine-year-old daughter whose parents both work at Boston’s Museum of Fine Arts (BFA). Her mom is due to give birth to her baby brother soon, and her dad, an art handler, needs to fly to Paris to collect pieces for a new BFA exhibit. After some great Paris sightseeing, Julieta and her dad are ready to pack up and head home – until she and her dad walk in on a burglar stealing the prized Regent Diamond! The diamond was going to be a key piece in the BFA exhibit, and all eyes are on Julieta’s father. Julieta starts putting together some clues, desperate to save her father’s job and reputation, all the while hoping they can get home in time to be there when her baby brother is born. With nods to to Greek mythology (especially the goddess Athena) and smartly placed clues that will lead readers to the answers alongside Julieta, this is a fun cozy mystery for burgeoning whodunit fans. Museum fans will love seeing what goes on behind closed museum doors – a realistic Night at the Museum, so to speak. I loved reading about Julieta’s goofing around with her parents in the museum and Back matter has the true story of the Regent Diamond, the goddess Athena, the art mentioned in Julieta and the Diamond Enigma, and a handy glossary of terms. A note at the beginning of the book has a helpful glossary of Spanish and French words, as words and phrases come up during the course of the story. A great book to introduce to readers that are moving from intermediate chapter books to more detailed middle grade fiction.
