*sneaks in to whisper* We are rearranging things for the release of the new version today. So the page says Out of Stock while we move things around to get them into place. *glances around to see who heard that secret update*
The first Nancy Gantz book is not listed because it was not available when I wrote the lesson plans originally, and because I didn’t want to incorporate a commentary all year long. The Genesis study already included a character study component, which provides a nice change of pace. I’m sure the Genesis commentary is just as good as the others.
The Peter Menzel books are featured in several lessons in the new Visits to Africa map notebook (actually, they will be featured in all the new map notebooks). You could skip those lessons if you don’t have those books, and you’re always welcome to substitute different living books that are available to you. We’ll have the sample for Visits to Africa up later today *glances around again* so you can take a look and see how those books are used.
