This is the last book of a series that really needs to be read in it's entirety to be fully appreciated. The Thoene's have left the door open for more, but I think this is truely the end of the series.
Never have I read a series that has touched me as much as these books have. They are written artfully, and with so much scripture it makes you want to go back to the source.
The research that went into these books is incredable.
One of the best things about the series are the study questions at the end.
I recomend this series as a small group study. You could do a book a month and spend the year in a deep and meaningful journey with Jesus and the people whose lives he touched while he walked the eath.
