Have you ever wondered what would happen if you were suddenly ripped away from everything you knew, dropped into a completely alien world, and slowly began to forget your own name?

That is the terrifying reality facing Astrid Mettlestone-Staranise in Jaclyn Moriarty’s spectacular new addition to the Kingdoms and Empires series. Published by Allen & Unwin, Astrid and the Accidental Slip Between Worlds is a breathtakingly whimsical, high-stakes adventure that will completely enchant you from the very first page.

Astrid has a brilliant magical gift: she can instantly tell when someone is lying. But that superpower can’t save her when she accidentally slips out of her magical realm and lands straight into our world. The real danger? Our mundane reality is actively stripping away her memories and her very identity.

While Astrid fights to remember who she is, her family is caught up in their own beautifully chaotic crises. Her sister Esther is trapped at a wilderness camp dodging Shadow Mages and household items falling from the sky, while her sister Imogen is tracking an evil True Mage at the Elven Games. They have no idea Astrid is even missing—and time is running out.

Moriarty’s signature Aussie wit, wildly inventive world-building, and breathless pacing are at their absolute peak here. It is a story about the unbreakable threads of family, the weight of truth, and the terrifying fear of losing oneself. It is laugh-out-loud funny, deeply moving, and utterly impossible to put down.

This book works beautifully as a standalone fantasy, but if you’re already a fan of the series, this might just be your favorite adventure yet.
