Zack Files 20: How I Went from Bad to Verse (The Zack Files)
By Dan Greenburg.
Description
Zack goes on a class trip, gets an insect bit, and suddenly can't speak a single word that isn't in rhyme. Talking like a modern-day Shakespeare may be fun at first, but not when you can't turn it off! What could be verse? How did this happen? And how can Zack make it stop? - from Amzon
