Book 27 of the Boxcar Children. I did enjoy this, however it is not my favorite of the recent ones it still is following the same structure and thus is far better than the earlier novels. What do you do when strange things begin happening in your campground? If you’re the Alden’s then you begin to investigate. This was one of the few where grandfather Alden was not just the 5 minute adult supervision that is so common in child-centric stories, albeit they do have to rescue the adults. All in all it was a good read and a recommend.
