This book desperately needs a new cover that more accurately portrays the complete amazingness contained within. Despite my adoration of The Wednesday Tales, I wasn't terribly excited about this book, but once you open the pages it takes a blender to your guts and you read the whole thing without blinking. It's terrifying, but it's not a "horror" story. It's a fantasy story, but it's different and unexpected with a whole world of bizarrely wonderful things waiting to leap out at you. It's a complete book, but I need more -- What happened to Clockwork Gabby to make her the way she is? Why does Arkadi have a meercat tattoo, and where has he been for forty years? What makes Theo so important, and what will Bea do next?
Goodreads lists what looks like a sequel, called The Sleeper's Moon, and some reference has been made to that book "coming out next October" (2011), but I can't find it anywhere.
Update: Turns out the sequel was finished and ARCs were printed, but then the publisher decided not to finish it. Thanks a lot.
