Will the reappearance of Keegan destroy Kai's life with Rayna?

Locked in a battle against the Katori Guardians, Kai, the headstrong Prince of Diu, must fight to claim his birthright, but gaining access to his magic will not be easy. In an epic struggle, he lays everything on the line to gain the power he needs to search for his mother, Mariana. With Rayna, the love of his life, by his side, he fights for the life he never knew he wanted.

When Kai meets his long-lost grandfather, Lucca, he realizes that Lucca has very different plans for Mariana's fate. Their lack of trust soon puts them at odds, but when it comes time to test his will against that of his powerful grandfather, will Kai be able to control his newfound abilities? And how could he have foreseen his choices would put him on a collision course with his murderous father, Keegan?

Caught up in a magical life, Rayna must discover her own identity and the range of her new powers. Although her adopted parents gave her everything, she always wanted to know where she came from. While finding her sister gave her comfort, coming face to face with her mother may not be all she hoped. With Keegan hot on their heels, Rayna does the unthinkable and may suffer the consequences.
