Here's a little blurb about it:
After Aneth's best friend, Geoffrey, disappears, her search for him
uncovers secrets she never dreamed could be true--fairies, a magical
Twisted Tree, an underground world of mystical creatures, and a
tyrannical Dragon Lord.
With her life and the lives of many others at stake, Aneth undertakes
a dangerous quest to cut off the Dragon Lord from his ultimate source
of power and defeat him once and for all. But will she be able to
complete her quest before time runs out, or will she remain forever
trapped in the world guarded by the Twisted Tree.
