The descendants of the Little Mermaid face deadly magic, shifting
alliances, and the dangers of forbidden love in this final installment
of the Mer Chronicles. Lia can't wait for her parents' coronation. Now
living in the sparkling palace beneath the waves, she sneaks off to
Malibu whenever possible to see Clay. Tucked away in an abandoned
seaside mansion, Lia and Clay devise a plan to ensure they can stay
together forever. But when an old enemy resurfaces, and Lia is
restricted to the palace for the safety of all Merkind, she and Clay are
ripped apart once more. She fears not only for Clay, but for her best
friend Caspian, who seems to be swimming down a dangerous path. He has
invited the conniving Melusine to the coronation ball, convinced she's
capable of change. And no matter how hard Lia fights it, showing up on
Caspian's arm is just the start of Melusine's insidious return to her
life. With threats Below growing more ominous by the day and a powerful
ancient ritual looming, soon the two girls can't escape each other. As
their fates grow increasingly intertwined, Melusine might be the only
one who can help Lia find the answers she desperately needs to save
everyone she loves and to achieve her happily ever after. But can Lia
trust her?
