Curiosity House Books in Order

The Curiosity House books are middle grade mysteries with a wonderfully odd setup. The series follows four children who live and work at Dumfrey's Dime Museum of Freaks, Oddities, and Wonders, a place packed with strange exhibits, stage acts, hidden corners, and more trouble than any reasonable person would want. Sam is astonishingly strong, Thomas can bend himself into impossible shapes, Pippa is a would-be mind reader whose gift never works quite the way she wants, and Max arrives as a knife thrower with mysteries of her own.

The museum is the real hook.

It is creepy, funny, cluttered, theatrical, and full of people who don't fit anywhere else. That matters, because these books are not just about clues and villains. They are also about found family. The children may be treated as curiosities by the outside world, but inside the museum they have a home, jobs to do, and people who understand what it means to be different. That feeling of belonging gives the series a warm center, even when the plots get dark.

The first book, The Shrunken Head, kicks things off with a stolen artifact and quickly expands into murder, conspiracy, and secrets about the children's pasts. Later books keep building from there. The Screaming Statue raises the stakes with a murdered friend, pressure on the museum itself, and deeper links between the central mystery and the children's histories. The Fearsome Firebird brings back the threat of Nicholas Rattigan, adds robberies and another murder investigation, and turns the whole story into a bigger showdown over loyalty, deception, and who can be trusted.

Across the series, each child gets moments to matter. These are ensemble books, and that makes them fun. One clue needs Sam's strength, another needs Thomas's agility, another needs Max's nerves, and sometimes what saves the day is simply Pippa refusing to stop asking questions. Their talents are entertaining, but the bigger pleasure is the way they learn to work as a team.

The tone sits in a nice spot between spooky and playful. There are dead bodies, threatening adults, and genuinely tense scenes, but there is also a lot of humor, sideshow weirdness, and affectionate energy. The books never forget that they are telling adventures for younger readers, even while they lean into gothic atmosphere and old-fashioned detective plotting.

If you want a series with misfit heroes, historical flavor, lots of secrets, and a setting that feels like a character in its own right, Curiosity House is easy to recommend. The mysteries are brisk, the world is memorable, and the emotional throughline stays clear: these kids are fighting for the truth, but they are also fighting for the place that made them a family.
