A great book will transport you to another world... literally, if you're not careful. On a gloomy Thursday afternoon, Max Bloom enters his local library in a last ditch attempt to stave off an epic case of teenage boredom. Among the hushed stacks he discovers The Cornerstone - an ancient book tucked away on a dusty, forgotten shelf. Opening the cover, Max is torn from the library into an alternate dimension full of things intent on killing him - thus avoiding boredom with remarkable success. He meets a beautiful girl called Merelie (brilliant), who tells him he's the only one that can save both their worlds from the Dwellers - hideous mind sucking creatures from beyond the universe (not so brilliant). Merelie thinks Max could be a Wordsmith, a sorcerer able to craft magic from the written word itself - one powerful enough to stop the Dwellers and their treacherous human allies. This all sounds completely unbelievable, of course. The kind of thing you'd read in a fantasy novel... but The Cornerstone doesn't lie - and the danger is very real. In a world threatened by monsters, where books are worshipped and magic exists, Max Bloom must make a choice: close The Cornerstone and run home - or trust Merelie, become a Wordsmith, and save two worlds from certain destruction...
