GOOD NEIGHBORS GN BOOK 01 KIN

"(W) Holly Black (A) Ted Naifeh Rue Silver's mother has disappeared and her father has been arrested, suspected of killing her. But it's not as straightforward as that. Rue is a faerie, like her mother was. And her father didn't kill her mother - instead, he broke a promise to Rue's faerie king grandfather, which caused Rue's mother to be flung back to the faerie world. Now Rue must go to save her - and must also defeat a dark faerie that threatens our very mortal world."
