Can one curse undo another?

When prim and proper enchantress Lady Alexandria attempts to bewitch a magic mirror, she ends up cursed—powerless, penniless, dumped in a strange land, and stuck in the body of an old hag.
As if that weren't bad enough, the mirror gives her two tasks: curse the prince whose arrogant cruelty she once ignored and find her way home—before the Magic Collectors find her and strip her of her powers forever and before the mysterious woodsman who finds her lost in the forest discovers who she really is.
The prince she curses must learn to love before an enchanted rose dies or he will remain a beast forever. Will her fate also be sealed when the last petal falls?
A clean and wholesome retelling of Beauty and the Beast set in a Regency-ish world and telling the untold story of the enchantress.
