War draws closer, like a tide to the shore. Bree and her friends have escaped the clutches of the Egrian King, but their troubles are far from over. Still reeling from the secrets that drew new breath when her father took his last, Bree sets off for the safety of Nereidium-- the kingdom she's just learned is hers. But with the King's ire at its peak and war a certainty, Nereidium is no longer safe. As Prince Caden rallies the Egrian people against his tyrant father, Bree, Princess Aleta, and Tregle race to the Nereid shore to warn them of the incoming danger—and to put the Nereid Princess on the throne. The only trouble there: Bree can’t bring herself to reveal that the Princess is her. It’s not a dilemma she can waste time pondering. With a new weapon in his arsenal, the King's strikes are sure to be bolder than ever before. And Bree may not be ready to wear a crown… but she won't let her kingdom down without a fight.
