This is a story about a world very similar to ours, with one exception: vampires live next to people and are full members of society. Vampires are not born - they become one after receiving the Mark. When the transformation begins, the newcomer has only two options: accept his new essence by going to study at the closed vampire school Abode of Night, or die. This is how sixteen-year-old Zoe Montgomery finds herself in the Abode of Night. However, she received her Mark in an unusual way, because she was chosen by the vampire goddess herself - Nyx. Now Zoe has to settle into a new home and find her place in the world of vampires, which turns out to be much more dangerous than she imagined.
