Megan's preparing to walk down the aisle with her triplet sisters as her bridesmaids when their long-lost grandfather Darkheart interrupts with staggering news: they are heirs of an ancient vampire-slaying legacy. One of them is a natural-born slayer. One is a healer. One will become a vampire. And they're all in imminent danger from the vamp who murdered their mother.
