War has come to the Enchanted Vale. Not only am I mates to three of the four High Princes, but I'm also the daughter of the lost Queen. This is my home, and I have to protect it. 

For months, I've been imprisoned in an underwater cell, and my mates are scattered across the realms, searching for me. The diabolic Kairyn and Nightingale have taken over the Summer Realm, and there's only one way to stop them. The true High Prince of Summer will have to reclaim his throne, and to do that, he's going to need his full strength.

Which means being with his fated mate…who isn't me. I always knew the day would come when I'd have to give Dayton up, but now that it's here, my heart is breaking. At least we have one last adventure together, as we must fight in the Sun Colosseum to reclaim the magical bow that only I can wield.

All the while, my mates battle for the Vale's freedom from across the realms. Keldarion and my father venture deep into the Below to search for my mother, the lost queen. Ezryn takes a hazardous journey with two young princesses into the unforgiving desert. And Farron must team up with the person he hates most in the world―the Prince of Thorns, Caspian―to confront a dark god who wants to claim the Vale for his own.

I know my Princes are counting on me to be strong. No matter what the Summer Realm throws at us―be it pirates, sirens, or gladiators―I'll fight for Dayton's home. And even though I know I shouldn't…I'll fight for his heart, too.
