Bewitched — Sandra Schwab

SWEET PASSION
After a magical mishap that turned her uncle's house blue, Miss Amelia Bourne was stripped of her powers and sent to London in order to be introduced into polite society--and to find a suitable husband. Handsome, rakish Sebastian "Fox" Stapleton was all that and more. He was her true love. Wasn't he?

OR THE BITTER TASTE OF DECEIT
At Rawdon Park, the country estate of the Stapletons, Amy began to wonder. Several inexplicable events suggested that one sip of punch had changed her life forever--that this love, this lust, was nothing but an illusion. She and Fox were pawns in some mysterious game, and black magic had followed them out of Town. Without her powers, would she be strong enough to battle those dark forces and win? And would she be able to claim her heart's true desire? Magic potion or no, what she felt for Fox was a spell that could never be broken.
