Elayne thinks the old family story that one of her ancestors stepped through a tapestry into a world of mythical beasts makes a great fireside tale. But she lives in the real world. In New York City. And she's outgrown that kind of fantasy.Until she finds herself in front of a unicorn tapestry at the Cloisters museum and sees her initials woven into the fabric. And hears a unicorn calling to her. And slips and falls - into that other world.Suddenly the line between fantasy and reality isn't so clear. But the danger is real enough. Almost before she can think, Elayne is attacked by a ferocious beast, rescued by a unicorn, and taken prisoner by a tyrant king. Each of them seems to have an idea about her - that she's a hero, a villain, dinner!But Elayne has a few ideas of her own. She wants to overthrow the king; she wants to tame the unicorn. She wants to go home! And she's willing to become both hero and villain to do it.
