Poison

Arthurian legend mixes with modern-day witchcraft in this haunting sequel to Legacy, which Publishers Weekly said should please the legions of paranormal fans looking for a sophisticated supernatural thriller.
After the riveting–and romantic–events of Legacy, Katy has won Peter’s heart and is now claiming her place in the magical world. Though half the students at her boarding school come from witching lines, the use of magic is expressly forbidden at Ainsworth, so as to keep the witching world hidden from the blue-blooded preppies, aka Muffies, who also walk the halls.
But the Muffies have at least a notion of magic, because Katy catches them staging a made-up ritual–and to her astonishment, the girls collapse at Katy’s feet and fall into comas. When Katy is blamed, she becomes desperate to clear her name and finds herself battling all odds to harness her growing magical powers in order to save the Muffies and dispel the Darkness once more.
