The Song of Embers: Starfell, Book 5

Fable and her friends are on a mission to restore her grandfather's memories.
There's only one thing in Starfell that can heal his magical injuries—the ashes of a recently reborn phoenix. They head out to visit Thorn's family in the Windswept Mountains, who can guide them to a phoenix's den near their home. But finding its ashes and unlocking their magic is not going to be easy. Especially with Endora vying for the bird's flames, desperate to use them to break her bond with the immortal dragon.
Can Fable and her friends reach the phoenix before Endora and find the key to unlocking its power?
