Dryadalis - Thirteen Thrones Saga, Book 1 #541210

Humans, elves, faeries and tides live together in the hustling city of Luzaria. But when Curfew rings, the streets are empty and from the dark walled off zone of Noctia, the gates are opened: necromancers, sorcerers, witches, vampires, werewolves and demons can stroll through at their leisure around the luzaran city, protected by the Common Law, that justifies any of their actions that takes place between midnight and the break of dawn.
And the situation is that luzarans and noctis have taken years taking actions with the goal of strengthening bonds between both worlds, divided only by the huge wall that encloses Noctia inside of it: The Empire of the Night. Common Law includes as well the so-called Commute.
June is a young human that will spend her next year living in Noctia, while Tayr, a mysterious sorcerer, will be in her home, under her roof, and next to her brother Adrien, whose curiosity over him will grow at the same time an uncontainable attraction does, but... Who is really Tayr?
