Blood Island

With Elizabeth on the loose and Byron free to roam the halls of headquarters, the Siren community is on edge, waiting for the impending first strike.
And it comes when three Elders are found dead after they go out for their monthly hunt.
Now, for the protection of the soon to be heir to the throne, Raya and her friends are sent to an unmarked island where Sirens walk in the sunlight without fear. It's their island.
And it might just be the key to a dark plan.
