Merlin is trapped in the shadows of a spell. His spell book, forged in the outer regions of Heaven, has a new master. Idwell Martin, of Arthurs bloodline, along with his twin, Gareth, have been summoned back to the Circle, where magic dwells. The forces of Terom are set to rise, Mirdrake as their captain. Idwell and Gareth have to remember all that they have been forced to forget. With the help of the Stephin and the dark Broodjin, Finstik and the blind witch Belliah, there is a chance that the Darkdwellers can be held back. But only if the book of Gobbledygook will reveal its secrets, and perhaps, call upon its ancient master.
