Her bestselling novel, Ashes, Ashes (Scholastic), was a White Pine award nominee, Snow Willow nominee, a Bank Street Best Children's Books of the Year 2012, and an American Booksellers Association Best Books of 2011. Her novella, "Love You Like Suicide," appeared in the Fierce Ink Press anthology Becoming Fierce: Teen Stories IRL, which was listed as a Best Teen Book of 2014 by Quill & Quire.
