There's something creepy about this tattoo

Wow.  If you're looking for a fantastic audiobook for someone in 7th grade or older, get The Black Tattoo, written by Sam Enthoven and read by John Lee.  Not only is the story very cool, but the narrator provides a phenomenal array of voices. Charlie and Jack are best friends in present-day London.  After being recruited into a secret society called The Brotherhood, Charlie ends up with a tattoo on his back...a MOVING tattoo. It turns out that an ancient demon - the Scourge - is possessing Charlie and has some truly nasty plans.  So it's up to Jack and new friend Esme (a girl with apparent super powers) to actually follow Charlie and the Scourge into Hell itself to stop them.  This sounds serious, but there's actually quite a bit of humor, both in the storyline and the way it's read.  This audiobook is long - almost 14 hours - but awesome for your next road trip.
