Doll Bones by Holly Black
In this Newbery Honor Award from the author who co-created The Spiderwick Chronicles, we follow Poppy, Zach, and Alice, who still play pretend even though all their peers have graduated to more age appropriate activities. Just when the reality of growing up begins to rip the group of friends from their world of pirates and battles, a real quest falls into their laps. Eager to hold onto their adolescence, and also find magic in the real world, these three set out to put to rest an earthbound spirit. This is a spine chilling, coming of age story that blurs the line between truth and fiction! I had a hard time reading this one before bed! It's definitely one for kids who don't mind some spookiness.
