A single kiss could be your last! Seventeen-year-old Layla grew up in a family of Guardians, a powerful race of gargoyles who hunt demons. However, she herself is only half Guardian. The second part of her - demonic - was inherited from her mother, the powerful Lilith. Like Lilith, Leila has the deadly ability to take the soul from those who have it. And the handsome Zane - her sworn brother, friend and protector, with whom she has been in love since childhood, becomes her unattainable dream. But then she meets Astaroth - the Supreme Demon, who, knowing about her secret, for some reason unknown to Leila, takes her under his care, saving her life more than once or twice. Astaroth does not hide his nature - a demon-tempter. And Leila can't resist. She dreamed so much about her first kiss. And demons, as you know, have no soul...
