Some homeschoolers really love this curriculum. One testimony that I read follows:

“The Mystery of History is a curriculum unparalleled in its field. Created as a guide through the annals of time, The Mystery of History will lead all ages clearly through the labyrinth that many find this subject to be.  Up until now, most world history and bible history have been separated.  Linda Hobar has taken the initiative to tell the whole story in a way that few have before. With a classical approach, she weaves the story line together of both world and Bible history in Volume I. Subsequent volumes continue to weave the message of the Gospel through the ages.

If history is taught in your home, The Mystery of History will unfold connections in history for you and your children like nothing else.  If you study the Word of God, The Mystery of History will give you a solid chronological foundation to build on.  There are no academic limitations to this syllabus. Designed to stand alone, each volume is as simple or as in depth as the individual or family wants it to be. This curriculum is the backbone from which any student can confidently grasp the mystery of history.” – Anne L.
