When the stars begin to die and an ancient world starts to awaken, four friends stumble upon a hidden door buried behind a lost waterfall. Ceren expected a final summer adventure before life pulled them apart. She did not expect to be dragged into Thrion—a lost realm of floating cities, living magic, and secrets older than creation itself. There, she discovers that she and her friends are tied to a prophecy that foretells either the salvation or destruction of an entire world. As ancient seals break, monsters rise from the shadows, and a long-banished king threatens to return, the four friends must uncover the truth of who they really are before Thrion falls into darkness.

Secrets. Conspiracy. Tension. Cora Flair has spent years searching for answers about her fiancé’s disappearance. He vanished during a routine boat trip, leaving behind only questions and an ache she can’t shake. Now a dedicated officer in the Coastal Patrol Unit, Cora’s mission to protect the coastline is also a personal one—to uncover the truth, no matter the cost. Her latest assignment forces her to investigate Kai Montague, a famous surfer suspected of being involved in a human trafficking operation. With his laid-back attitude and reputation for keeping secrets, Kai is the last person Cora wants to trust. But when the investigation uncovers links between Kai and several missing persons, including her fiancé, Cora has no choice but to dig deeper. As she works to uncover the truth, Cora begins to see a different side of Kai—one that raises more questions than answers. Is he a key to solving the case, or is he hiding something darker? The closer she gets, the more dangerous the investigation becomes, threatening not just her career but her life. Cora must decide how far she’s willing to go to find out what really happened in the past, even if it means confronting truths she isn’t ready to face.
