The Mystery of History by Linda Lacour Hobar

My boys and I are currently using Biblioplan for our History and Reading curriculum.  If I see The Mystery of History for sale somewhere I will buy it as a supplement.  I like how Mrs. Hobar includes all activities/reviews/test questions in one volume.  She also writes in a fun, engaging manner.  Not many pictures or photographs are included (compare to Biblioplan).  The literature selections/suggestions are sparse compared to Biblioplan.
