Barbed Wire Islands

Mirasol Matapang is a fifteen year old with crippling anxiety who finds herself trapped on a prison island where half the people turn to monsters at night. Santiago Guerrero de Reyes is the only reason Mirasol made it to the island alive, and he's one of the unlucky souls that turns into a monster at night. The two form a bond thanks to their strong will to survive the nightmare they entered together, but they find themselves in different camps on the brink of war.
The human camp is preparing to kill all the monsters on the island in exchange for a way home. As much as Mirasol wants to leave, she refuses to do so without Santiago by her side. Mirasol and a few others are against this plan, but open opposition will result in death. Mirasol tries to get information to the monsters to keep them safe, but she's no spy. Her actions are putting her life in danger, and the only way she'll survive is if her allies step up and find another way to escape.
