This is the fifth and final, fantastical adventure from the phenomenon that is Pseudonymous Bosch, author of the hilarious bestseller "The Name of This Book is Secret". When Cass, Max-Ernest and Yo-Yoji are accused of stealing a very-valuable-and-not-to-be-touched Ancient Egyptian mummy from the local museum, they're determined to get to the bottom of the mysterious case. But after they are accidentally trapped in a crate with a mummified cat, the three youngest members of the Terces society unwittingly find themselves on their way to the great pyramids of...Las Vegas. Amongst the dusty corridors of the Cairo Hotel and mysterious hieroglyphs of the Nile Nail Salon, Cass draws ever closer to uncovering the Secret. But so too do their sneaky arch-enemies, the Masters of the Midnight Sun...Can Cass defeat Lord Pharaoh once and for all, and will we all finally, conclusively, and at (very) long last, learn the Secret? You'll just have to read this! Bursting with inventive characters and laugh-out-loud moments, readers will be instantly hooked by the stylish, tongue-in-cheek story-telling of Pseudonymous Bosch.
