The highly anticipated sequel to the award-winning and bestselling futuristic musical fantasy series by Emmy-nominated composer and acclaimed songwriter Shaun Barrowes.

After a narrow victory in Round One of the Siren Games, Kassiana Rivernova faces her greatest challenge yet in Round Two: The Abyss. Haunted by her team's high expectations and the traumas of her recent past, Kassi must hold her focus-even as deepening bonds test her heart and the deadly trials of The Abyss push her limits.

Meanwhile, Amára Rivernova races against time to rescue Enzo from the the U.N.O.E. Her only hope lies in an unlikely alliance with Enzo's enigmatic brother, Nikola. Together, they must infiltrate the most fortified prison on Earth before Enzo disappears forever.

Caught between Ravana's Revolutionaries, President Odyssey Nines and his mediation officers, and the Council of Creators, Kassi and Amára are swept into an intergalactic power struggle where nothing-and no one-is what they seem. As betrayals surface and loyalties are tested, the dream of returning to Paradise slips farther out of reach.

In this gripping sequel, Kassi and Amára must navigate impossible choices, where survival, love, and loyalty collide and the dream of Paradise may cost them everything.
