FIVE ROYAL SISTERS. ONE CROWN.

They are the daughters of a king. Though they share the same royal blood, they could not be more different. Bluebell is a proud warrior, stronger than any man and with an ironclad heart to match. Rose’s heart is all too passionate: She is the queen of a neighboring kingdom who is risking everything for a forbidden love. Ash is discovering a dangerous talent for magic that might be a gift—or a curse. And then there are the twins—vain Ivy, who lives for admiration, and zealous Willow, who lives for the gods.

But when their father is stricken by a mysterious ailment, these five sisters must embark on a desperate journey to save him and prevent their treacherous stepbrother from seizing the throne. Their mission: find the powerful witch who can cure the king. But to succeed on their quest, they must overcome their differences and hope that the secrets they hide from one another and the world are never brought to light. Because if this royal family breaks, it could destroy the kingdom.
