THE HOUSE WITH NO KEYS (THE DELTA GAMES, 2) by Lindsay Currie, Sourcebooks Young Readers, Sept. 30, 2025, Hardcover, $16.99 (ages 8-12)
A group of friends race to complete the most challenging escape room they’ve ever faced…and confront their fears in The House with No Keys, by Lindsay Currie.
It’s been just over a year since Sarah, Hannah, and West made it through the epic funhouse that changed their lives forever. Since then, the three best friends have been working for Mr. William Taters, the owner of that very funhouse, renamed The Delta Game, and completing every challenging escape room they can.
But then a strange invitation shows up from the ominous and cryptic owner of a new funhouse―The Mystery Mansion.
The Mystery Mansion claims to be the biggest and best escape house ever, and it’s opening just miles away from The Delta Game. The mysterious owner has invited the trio to come test it on opening day, offering a ten-thousand-dollar prize if they successfully escape. The prize is exciting, but the three friends don’t want to be a walking advertisement for a competitor to their beloved The Delta Game.
But maybe the only way to keep their funhouse in business is to accept the invite, escape the mansion in record time, and show just how boring and easy it is by comparison. The trio arrive on opening day, armed with their “fortune favors the bold” attitude. Unfortunately, their plan quickly goes awry. Secrets threaten their friend group, nothing in the house is as it seems, and this time, not everyone is playing fair… —Synopsis provided by Sourcebooks Young Readers
The House with No Keys is the second book in Lindsay Currie’s The Delta Games series. The first book, The Mystery of Locked Rooms, that follows three friends as they search for a hidden treasure in an abandoned 1950s funhouse. The House with No Keys is a separate “locked room” adventure, but it does build one relationships and outcomes from the first book.
Both books are built on Sarah, Hannah and West’s friendship. The mysteries and puzzles would be just that if not for them. They’re smart, thoughtful and have learned to work as a team. Currie not only touches on solving the puzzles but problem-solving within relationships without it feeling fake.
The Deltas (as the trio is known) are experts at escape rooms, and solving the funhouse mystery made them famous. But that doesn’t mean that things come easily. Mystery Mansion is unlike anything they’ve ever faced, and each friend’s specific talents are needed in order to win.
The House with No Keys feels different from The Mystery of Locked Rooms. The characters are older and some more “romantic” feelings come into play. Mystery Mansion and its rooms also take on a darker, almost meaner, tone that makes more sense once read in entirety.
As with The Mystery of Locked Rooms, Currie’s writing in The House with No Keys is inviting — she immediately helps readers settle in for a fun ride. Her pacing is strong and she balances light and dark, frustration and joy well.
The House with No Keys is a strong follow-up that should appeal to fans of the first book.
