Suzanne Sheran, with her experience as an elementary school teacher had put together an engaging story where her protagonist Nat, or is that Gnat, along with his friends the Gnus, get into trouble dealing with difficult words with silent letters, and of course the dreaded homophone where words in different contexts are spelled differently.

Oh dear! It was not a good day for Nat Newman.

Mrs. Nash at Newton School was having a spelling bee. It was Nat Newman's turn and his word to spell was...

Gnu

Nat went nuts! When he got home he found some very upset gnus that went on a bit of a rampage introducing Nat to animals and objects that have silent letters or more than one spelling. 

Beautifully illustrated by Mark Beech this book is an ideal reader for school or at home.
