Now, Aila and her cousin, Persephone, act as representatives for their grandfather, King Gaspar, to the human world. The mermaids share a close bond with the Prince Jarek, but when Alia catches Persephone trying to siren him into the waters, she must work to protect her friend from her cousin without hurting the human-mer relationship—something Persephone’s mother won’t tolerate. War is brewing and Aila and Persephone are caught in the middle of a battle they never saw coming—one that will last for another century. Every war has an origin...she just never thought it would be her. less

Over the years, select mermaids from the royal bloodline have been trained as spies to work for the reigning kings and queens, keeping the collection safe from sirens and humans. Celena and her partner, Merrick, work covertly for the royals—not even her twin brother knows... moreWar has hovered around the kingdom of Scylla for generations ever since the original sirens left the mer collection generations ago after nearly drowning the human prince.

As she fights to save her sister, the royal mermaid is forced into deadly encounters with anything that gets in the sirens’ way, taking the brunt of the trauma as she tries to protect her little sister and escape the sirens’ revenge. She quickly learns that the attack on the palace in Scylla wasn’t the only thing Tarni and Nir had planned—they intend to use Celena and her sister for an even darker purpose—starting a battle with the humans. When Merrick, Caspian, and Llyr try to free Celena and Coralie, they disrupt the sirens’ plans and find themselves in the middle of a war with both their enemies under the sea and the humans above the waves. As the collection closes in to aid in the rescue mission, they find themselves in a deadly siege above the surface that can only end in destruction. The Siren Wars are nowhere near over. less
