This was the 11th Reacher book I have read, and although I have not been reading them in order, I did prefer this to some of the more recent Books such as "A Wanted Man".As a huge Reacher fan I always prefer the books where we find out more information about his time in the Army and previous relationships. There are two things which make this book important to the Reacher legacy, the time he spends with his brother and mother and the career decision he makes at the end.The time spent with Joe, magnifies the differences in their personality and allowed me to better understand the comments he makes in previous books regarding their relationship. The book also introduces his mother and gives further insight to Reachers childhood, for me the best part was finding out that his mother always referred to him as 'Reacher'.Regarding the Career choice ill let you find that out for yourself!
