To save Keanu's life, Leilani has sacrificed herself and agreed to become the Bride.

As the Twins take her to their castle in the ocean, Leilani soon discovers truths and secrets about both the brothers and herself which she never imagined.

When the Twins announce that the wedding will take place in two days, Keanu gives in to his raging anger and slips back into his dark past in order to be the savior he promised Leilani he'd be — while receiving unexpected help from a mysterious force in the ocean.

But perhaps Leilani can be a hero herself, as the powers of the sea grow stronger in her veins.

The waves are rising.
The ocean is awakening.

It seems that not only Leilani's letters bind her and Keanu's destiny together.

So do the Twins.
And so does the Crown.
