Soul of cinder

Angelyne, Mia and Pilar find themselves challenged by the returned Prince Quin, and their clashing powers tip the elements of all four kingdoms out of balance. In an attempt to put things right, the sisters travel to the glass kingdom, each suffering from both their own burdens and the aftermath of their feelings for the prince. It's enough to make them investigate rumors of an island that can erase all pain -- if they're willing to pay the price.
