Measle and the Wrathmonk by Ian Ogilvy

My review

rating: 5 of 5 stars
Plenty of action to keep the interest for the most reluctant readers but still smart and twisted enough for sophisticated kids. Frightening premise : Basil Tramplebone (Wrathmonk = evil, insane wizard) is the guardian of a child, Measle, who has to figure out how to survive under his twisted "care", and, many times, how to escape his wrath. I'd recommend for 4th - 6th grade, but it depends on the kid.
