The Whisperer is a 2009 fantasy novel aimed at pre-teens and teens (ages 9–14) by Fiona McIntosh.
It follows the adventures of Griff, a thirteen-year-old boy who works in the circus, and Lute, Crown Prince of Drestonia.
When the circus master discovers Griff's amazing ability, he forces the young boy to appear in his show.
Griff knows what he is doing is wrong and escapes from the circus with Tess, a fellow performer, and her magical creatures.
With the help of his friends, magical and human, Griff realises that the Whisperer, whoever he is, is in great peril, and that it is up to him to save the mysterious voice.
