Naming of Tishkin Silk by Glenda Millard

Griffin has a secret in his heart that nobody else knows - until he meets Layla.

Griffin Silk is an uncommon sort of boy, from an uncommon sort of family, and when he meets Layla, a princess with a daisy-chain crown, he knows he's found a friend. 

So Griffin shares his inner thoughts with Layla and together they find a way to deal with his secret. Just like the mythical beast whose name he bears, Griffin has uncommon courage and the heart of a lion.

But it will take a friend like Layla to help him find the answers to his biggest questions.
