In a glittering underwater world, where danger lurks behind beauty and power, seventeen-year-old Miranda Sun must decide between her freedom and the love her heart ultimately yearns for.

When Miranda Sun returns to Marin on the eve of her eighteenth birthday, this time of her own free will, she quickly learns that her worst fears have been realized. The glittering underwater city is not as she had left it, nor too is Marko, the young king who has dominated her thoughts and heart for the last twelve months.

To make matters worse, Miranda has not made the journey to Marin alone, and now must contend with not only Marko's evil brother Damir, but more surprisingly her sister Lauren who has an agenda of her own.

With Marko's power beginning to wane, and with cracks beginning to show in the domed Utopian city, and veiled danger lurking everywhere, she quickly learns that in this dazzling city full of beautiful people she can trust no one but herself.
