Fairy Haven and the Quest for the Wand — Gail Carson Levine

"Beware a mermaid's wrath!"

The mermaid Soop has sent a flood to Fairy Haven! Water-talent fairy Rani must bring Soop a wand or the Home Tree and all the Never fairies will be swept away.

But wise Mother Dove isn't sure which is worse, a wand or a flood. Wand wishes, tantalizing wand wishes, are risky. The most innocent wish can cause untold trouble. And not even Mother Dove knows that wands have hearts and minds -- kind hearts or cruel hearts, sympathetic minds or minds filled with spite and mischief.

Rani, Tinker Bell, and Ree, queen of the Never fairies, set out on a perilous quest for a wand, a journey that takes them across an ocean to the palace of the terrifying Great Wanded fairies. Many obstacles stand between the questers and success: Tink's disappearance, a mermaid's magical song, wand madness, and even Never Land itself.

Meanwhile, the floodwaters are rising. . . .
