Book IV in the The Tales of Dreamside Series: This is the story of Keaghan and his adventures in Dreamside. Dreamside is a strange world of twisting hallways, a labyrinth just beyond the walls (and through and between also) of your own home. In the world of Dreamside, Keaghan met the Knitters (or the Aos Si as they like to be called) who knitted the holes in reality. You haven't seen any holes in reality? Then your home must have really good Knitters! Keaghan now discovers that there is a world beyond Dreamside, full of vicious creatures called Tomsi which collect the teeth of children. Keaghan has escaped the terrible maze of the Blether House, the home of the Tomsi, but his escape is short-lived. He comes face-to-face with the masters of the Tomsi - the feared Cra-gin and learns of their plan to destroy the Heart of Dream itself. In Book IV, Keaghan will travel to the House of No and then to Overside in an race to return to his own home and save his family from the Cra-gin's invasion.
