A creaky attic, an ornately carved suitcase, and one pulse of blue-white light, that's all it takes to fling Noor, her partner-in-mischief Sem, and an unexpected ally into history's deep end. Each turn of the rusty key drops them in a new era with a single rule: find the next crystal shard before the clock, and the world around them, cracks. Ancient deserts, storm-lashed castles, neon skylines of tomorrow... every stop packs riddles, rivalries, and a few creatures you really don't want to meet in the dark. The mysterious Timekeepers insist the kids are "guardians in training," but fail to mention what happens if they mess up. And with the crystal whispering temptations to rewrite fate itself, the trio must decide how much of the past, or future, they're willing to risk. Fast, funny, and fizzing with danger, this is a passport to everywhere you've ever dreamed of going, and plenty you haven't. Snap the clasps, feel the hum, and step through... if you're brave enough.
