Danger. Deception. Duets. Genevieve Castle is finally getting her balance. Graduated on the honor roll, set up with a dream internship with the finest composer in Cierdeep, and firmly almost-serious with Sean, the world looks bright until the ocean insists on crushing her world and everyone she loves. Then there's her old obsession with Soremni Prince Oliver and his diamond green eyes. Until they find a cure, she'll never have Sean, not for real, not forever. Between assassination attempts and weird Soremni marriage customs, Gen must navigate a world filled with monsters, madness and epically deadly duets.
