4 Good Books: "The Haunting of Derek Stone" Series

I recently read 4 Scholastic novels (written for teens) by Tony Abbott. The books are in a series called "The Haunting of Derek Stone" and are well-written and hold your interest. You have to read them in order, however, or you could get somewhat lost. They premise is of a 14 year old, out of shape boy (Derek Stone) and his older teen brother and father take a train ride in Oregon, and the train goes off a bridge, killing people. All of the family seem to survive the accident. However, it turns out that an accident that occurred in that same spot, in that same manner in 1938 that was carrying prisoners - allowed the souls of the dead prisoners to linger and reanimate the newly dead victims (they refer to it as "translation of spirits" of the present day train accident.
The books build up the mystery, and I won't give it away. One of the reanimated dead, however is a prisoner who was a pyromaniac in 1938, and who leads the army of reanimated dead against Derek Stone (because he's "special"). Derek's brother Ronnie is reanimated by a good soul of a former prison security guard, and helps Derek and another train passenger. Again, I won't give away any more.
-I've noticed that you can find these as used books very cheaply, and they're worth the read. Enjoy them then give them to your teenager to enjoy. :)
