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.

Out of curiosity he took a peak at the demon king and came to find Damien Umbra (23-28) sultry, charismatic and flirty king of Hell.

After a second encounter with the demon king that resulted in heavy flirting, much to the new kings surprise, they had not met again for weeks. A single gift led the king to make a secret visit to Hell to interrogate the other king. During this visit Damien plays off his interest in the angel as only a fun game. This is to go on for years with only brief visits and gifts, causing the angel king to slowly fall for Damien in the process. Damien visits Ashton in the night, leaving a small gift for the angel to wake up to.
