This is a story about two girls who grow up in present day, spinning tales of magic and magical places. Then one of them gets swept away into the an alternate land and the other has to go find her and bring her back to present. This is an early urban fantasy novel.
Ariane and Sylvie had spent endless hours spinning fantastical worlds out of the depths of their shared imagination. But when Ariane returned for a long overdue visit, she found herself swept up by old Sylvie-sung spells, caught by the same madness -- or was it magic -- that still possessed her friend.
