I saw these magnificent paperbacks in London. They sound like academic fantasy-adventure novels. In Mr Y, the heroine reads a cursed book and can then enter people's consciousnesses undetected. In Tragic Universe, which comes to the US in September, the heroine is asked to review a book that promises eternal life. And in Popco, the earliest to be published, the heroine, a brilliant puzzle-solving toy inventor, attempts to create a new toy craze for teenage girls while trying to solve a centuries-old puzzle left in a locket by her grandfather.
