A week or so ago I posted in another forum asking about children's books set in the pines. There is a brief review there. I read Shadow in the Pines about a year ago and just got a copy for myself. I am in the process of reading it again. It is probably written for middle school kids, but I think you will still find it kinda neat.
Incidentally, the person who put me on to the book had it read to him (and his classmates) by his middle school teacher in Medford Lakes back in the late 60's/early 70's.
It is an adventure book that mentions many actual places in the pines. The main character (Ted) must live somewhere near Chatsworth but he travels all over the place. What seems to be a description of Apple Pie Hill is referred to as Muffin-Top Hill. I don't know if many fictional places are added to the story or if there was actually a Muffin-Top Hill with a fire tower on top in the neighborhood of Chatsworth. Even if some of the places mentioned are fictional, the descriptions are remarkable close to real places (like Martha, etc.). Surely it's worth a read. however, I have seen it for sale on ebay in excess of $100.
