"The central conceit - that certain people, known as Animare, are able to bring to life any picture they draw - is interesting and explored well, and the main characters, Matt and Emily Calder and their hearing-impaired friend Zach, are appealing and given convincing dialogue. The plot, meanwhile, sees sinister forces aligning to exploit the children's powers to open up a netherworld full of demons and there's a good use of lesser-known beasts from myth and fable"
