Princess Lavender Haynes is starting her new school year at the supernatural university of vampire werewolf and sorcery called Blackthorne university. In her first year at Blackthorn University, Princess Lavender Haynes is haunted by a relentless nightmare: a shadowy forest under a blood moon and a dark ritual involving her father, the legendary sorcerer and vampire Arius d'Angelo. The visions intrude on her daily life, affecting her concentration and peace of mind. Desperate for answers, Lavender turns to her friends-Bellarose, Lyra, and Astrid-for help. Their search leads them to Dreamweaver's Haven, a mystical shop run by a retired dream sorcerer, Professor Eldric. Accompanied by Jasper Skullridge, her betrothed and protector, Lavender and her friends delve into her dreams with Eldric's guidance. The sorcerer reveals a chilling prophecy: the ritual signals an imminent danger tied to the upcoming Blood Moon Festival. As the darkness of the ritual looms, the friends uncover that the threat may be more personal and dangerous than they imagined. With Jasper's protective presence and her mother, Queen Vampire Selene Vavardi's distant support, Lavender and her coven must confront their deepest fears and navigate a web of magic, friendship, and dark secrets. As they prepare for the festival, they must unravel the mystery behind the ritual and stop the dark force before it consumes them all.
