Jennifer's bio: USA TODAY BESTSELLING Author Jennifer lives in Martinsburg, West Virginia. All the rumors you've heard about her state aren't true. When she's not hard at work writing, she spends her time reading, working out, watching really bad zombie movies, pretending to write, and hanging out with her husband and her Jack Russel Loki. Her dreams of becoming an author started in algebra class, where she spent most of her time writing short stories....which explains her dismal grades in math. Jennifer writes young adult paranormal, science fiction, fantasy, and contemporary romance. She also writes adult romance under the name J. Lynn. She is the author of the COVENANT Series (Spencer Hill Press), the LUX Series (Entangled Publishing), and the upcoming YA contemporary mystery/thrillers DON'T LOOK BACK (Disney/Hyperion Spring 2014) and yet untitled book (Disney/Hyperion tentative Fall 2014).
