As a little girl, Olivia was convinced that supernatural creatures were real. After all, she had met a werewolf in her own backyard. Unfortunately, no one believed her. She lost all of her friends at school for being the weird girl, and her parents were convinced that she was insane. A decade of research and searching went by until she finally found him again. Her mate. The Alpha. When her family hears that she is talking about the existence of supernatural creatures again, they decide that enough is enough. Since going to doctors and therapists didn't work, they decided to send her away to the only place that could help her, and protect their other daughter from Olivia's instability and hallucinations. An asylum. Alpha Gabriel is livid and wants his mate back. When he finds out the love of his life was taken away, he prepares his army to do anything that it would take to get her back.

In a war-torn world where supernatural beings known as "subnaturals" or "subs" have emerged from hiding, triggering a global conflict that has claimed hundreds of thousands of lives, eighteen-year-old Lena Hargrove has spent the past six years as a ward of the state following her parents' deaths. Renowned as war heroes who sacrificed themselves to rescue their daughter from kidnappers, Lena's parents were largely absent throughout her childhood, leaving her with complicated feelings about their legacy and her own identity. As Lena struggles to understand her newfound identity and the abilities that begin to manifest, she uncovers a web of secrets about her parents' true role in the war. They weren't just fighting for humanity; they were part of a hidden movement working toward peace between humans and subnaturals. More importantly, Lena learns she was kidnapped not by chance. Hunted by extremists from both sides who either want to use her power or eliminate her entirely, Lena must navigate a dangerous landscape of political intrigue and ancient supernatural factions. Along the way, she assembles an unlikely group of allies—humans sympathetic to the sub cause, subs living in hiding among humans, and others like her caught between worlds. As her powers grow and her understanding of both sides deepens, Lena realizes that ending the war might require more than diplomacy or combat—it might demand a fundamental reimagining of what it means to be human or supernatural in a world where the boundaries between the two are increasingly blurred. But to fulfill her destiny, Lena must first confront the truth about her kidnapping, her parents' sacrifice, —a truth that will test her loyalty to both sides of her heritage and force her to decide what kind of world she wants to fight for.
