Odd & True

Gilded Age sisters face terrible monsters and their own haunted past in this "thought-provoking, atmospheric, and utterly bewitching" YA novel (Booklist, starred review).
Growing up on their family's Oregon farm, Trudchen Grey believed every word of her older sister Odette's fantastical stories. But now that Tru's gotten older, she's starting to wonder if those tales of their monster-slaying mother were just comforting lies. There's certainly nothing fantastic about Tru's own life—permanently disabled and in constant pain from childhood polio.
In 1909, after a two-year absence, Od reappears with a suitcase supposedly full of weapons—and a promise to rescue Tru from the monsters on their way to attack her. But it's Od who seems haunted by something. And when the sisters' search for their mother leads them to a face-off with the Leeds Devil, a nightmarish beast that's wreaking havoc in the Mid-Atlantic states, Tru discovers the peculiar possibility that she and her sister—despite their dark pasts and ordinary appearances—might, indeed, have magic after all.
