Mister Monday (Keys to the Kingdom, book 1)

by Garth Nix

Seven keys. Seven Days. A mysterious Will. And one boy. Arthur Penhaligon is about to embark on a fantastical adventure of magic and mystery. Strange things begin to happen after Arthur recovers from an asthma attack on the first day of school. He wakes up to find a mysterious key in his hand. Suddenly a weird new house appears in his neighborhood that no one else seems to be able to see. Upon entering the house, Arthur gets lost in a world of magical creatures and must find his way out before the terrible Mister Monday can steal the key away from Arthur. In this first of a seven-books series, Nix's imagination once again takes readers on a journey of excitement and suspense.
