Jael has always felt like a freak. She's never stayed in a town for longer than a year, she's never kissed a boy, she never knew her mum, and her dad's always been super-strict, but that's probably because her mom was a demon, which makes Jael half-demon, and most definitely not a normal sophomore at St. Mary's High School. Jael thought she had it under control, though, until her sixteenth birthday, when a mysterious present unlocks the story of her family's dangerous history and Jael's untapped potential. She discovers that the reason her family moves around a lot is because they're being chased by a particularly vindictive Duke of Hell, Belial. Jael must learn to master her demon side in order to take him on, while also dealing with a twisted priest, best friend drama, and the spacey blonde skater boy who may have hidden depths. In this paranormal YA novel, Jon takes on the dark side of human nature and the risks of believing dogma blindly, as well as the immediate threat of the pantheon of demons that are trying to meddle with humanity. With Jon's funny, heartfelt prose, Jael's story soars.
