Walter Moer Books - suitable for what age please?

[FranSanDisco]

Is anyone familiar with the above author? Dd 10 yo has been given a book by a relative called 'Alchemist's Apprentice'. I know I'll have to have a flick through but I have assignment deadlines for university looming for this weekend and can't face any more books added to the pile in front of me! So if anyone can shed any light I'd be most grateful .
