Turning thirteen starts off with a bang for Lily. Literally. A birthday present explodes on her porch . . . and soon after a trio of leprechauns (yes, leprechauns) appears in her bedroom. They whisk her away to a land of clover, piskies, a new friend, a cute boy, and lots of glimmering, glittering gold. A world of Green.
It turns out that Lily, like her grandmother before her, is next in line to be keeper for the Clan of Green, and in charge of all their gold. That is, if she passes three tests. And she has to pass them. Because if she doesn't she may never get to go home again. She'll be stuck with the Greens.
