My study group is presently studying 1&2 Samuel and we are diving into all the questions. Even if it's going to take us longer than the required time. It's got great discussions happening in our group. You may enjoy studying it as well!
The new 1-2 Samuel text has the features of other books in this series. Each lesson is long - takes several hours to properly prepare, and is not fully covered in an evening as too much would be missed. We took 3 nights to cover Lesson 1 of 8. Because of content and explanations, we would heartily recommend this new book to others.
