The Westing Game by Ellen Raskin
This enduring Newbery Medal-winning classic is often considered the gold standard of middle-grade mysteries. The story kicks off when an eccentric, wildly wealthy millionaire named Samuel W. Westing passes away and leaves behind a bizarre puzzle instead of a straightforward will. Sixteen wildly diverse heirs are unexpectedly brought together in a massive apartment complex to play a high-stakes game. Paired up in unlikely teams, the heirs are given clues to determine who among them is responsible for Westing’s supposed murder. Filled with wordplay, red herrings, and highly complex character arcs, The Westing Game teaches young readers to pay close attention to even the smallest details. Escape from Mr. Lemoncello’s Library by Chris Grabenstein
For young readers who love games and interactive puzzles, this novel is an absolute delight. Kyle Keeley is a massive fan of board games, and his ultimate hero is Luigi Lemoncello, a world-famous game maker who has just designed the town’s newest, most spectacular public library. Kyle wins a coveted spot at an exclusive sleep-in event to celebrate the library’s grand opening, but there is a catch. The next morning, the doors are locked, and the children must use their wits, scavenge for clues, and solve intricate riddles to earn their way out. Escape from Mr. Lemoncello’s Library perfectly blends literary trivia with high-stakes escape-room mechanics. The Mysterious Benedict Society by Trenton Lee Stewart
