When a desperate and beautiful young woman makes a dangerous pact with a sly Leprechaun, she finds herself under a spell that threatens her very freedom—and her only chance of true love. Aisling Ahearn's hand in marriage had been promised away to forgive her father's debts. But Aisling had always wanted to marry for true love—and took a terrible risk, trusting a Leprechaun's magic to save her. Now, trapped in the faery world, suspended in eternal youth, the only way Aisling can escape is to fall in love with a mortal within one hundred years. Unfortunately, mortals only see her as a white mare—except when she appears under the light of the full moon. It seems hopeless—until she meets Conlan Sloan, a bitter but passionate young man who awakens her faith in love. Their moonlight romance is fleeting—Conlan's time in Ireland is all too brief. When he finally returns to Aisling, it is 1999, with only two moons left to win Conlan's love forever.

When Erin McKeogh leaves Silicon Valley for Ireland, it's not for a vacation—it's to stop a wedding. Her best friend, Conlan Sloan, just announced his intention to wed Aisling Ahearn, a woman he's only known for two weeks! And Erin knows that wise people don't rush into things like marriages, and they certainly don't fall in love in fourteen days. If she's a true friend to Con, she'll stop him from making a terrible mistake, especially when in involves a rash marriage to an Irish gold digger. Then the disarmingly charming Phelan McDermott sets his blue eyes on her—and sparks begin to fly. Erin didn't come to Ireland to find love—she came to fight it. But even though she intended to stop a wedding, she may just end up planning her own.
