It's a good day for flying with the ravens: pale-blue sky, wispy clouds, gentle updrafts. It's also the last ordinary day before everything changes forever. To Nettle and her cousin Bracken, the youngest witches in the coven, the world outside their hidden valley is enticing, mysterious, and forbidden; but they never imagined they would ever see it. Then suddenly the veil that protects their valley is broached and the Wellspring Water needed to repair it is polluted, forcing them to travel to a human city in search of the Door to another world. A wishing necklace, seeking stones, a wily raccoon, human Witchfriends, and long-lost loved ones help Nettle and Bracken on their quest. Will their fledgling magic be strong enough, or will encroaching human civilization spell the end of Witchkind?
