Mirrorshade by Mike Wilks
The final thrilling adventure in Mike Wilks' trilogy of fantasy stories for fans of Charlie Bone. Imagine being able to step into a painting. This is the Mirrorscape. Something has gone terribly wrong. Mel and his friends have been locked in Deep Trouble prison in the Mirrorscape, while their evil Mirrorshades - who look exactly like them - are free to cause havoc in Vlam. Luckily, their old friends Goldie and Pilfer - the invisible burglar - are on hand to help them break out and try to prove their innocence. But arson, forgery and theft are the least of what their doubles have been up to. They're involved in a plot that could destroy our heroes. The race to find the mysterious Mirrortree is on! Can the real Mel, Ludo and Wren defeat their enemies in time? A world where angels, pyramid mazes, imaginary monsters, talking houses and - most importantly - the simple paintbrush all combine to form a series of hugely original and deeply compelling fantasy books for children.
