An ancient prophecy. A harrowing battle. A gut-wrenching loss. A destiny fulfilled.

Now that Sierra knows the truth about what happened to her family, she faces a new challenge. If she embraces her gift of hydrokinesis, she can finally extinguish the flames that threaten so many. But Excalibur is a formidable opponent, who will stop at nothing to usurp ultimate control and annihilate anything and anyone in his wake.

Left with no other choice, Sierra must relinquish her guilt and summon the courage to bring an end to Excalibur's brutal reign, but she'll need help. Dante's love for her is immeasurable, but is it, coupled with his deep-seated desire to protect her at all costs strong enough to withstand the storm they'll soon face, or will Excalibur's mighty dark forces and dogged determination prove too powerful?
