Witchling

Meet the D'Artigo sisters: half-human, half-faerie, they're savvy-and sexy-operatives for the Otherworld Intelligence Agency. But their mixed-blood heritage short-circuits their talents at all the wrong times. Delilah shapeshifts into a tabby cat whenever she's stressed. Menolly's a vampire who's still trying to get the hang of being undead. And Camille is a wicked-good witch, except her magic's as unpredictable as the weather, as her enemies are about to find out-the hard way.
