I'll start by admiting that I'm not exactly an Andrew Jackson fan. He seems to me to be arrogant, egotistical and has a habit of refusing to listen (with any real seriousness) to differing views on a subject once his mind is already made up. I still hold these views, but Remini presents to us a man who is much more than the one-dementional figure described above.
Like most, I have low expectations of a book that is a one volume version of mulitple volumes (Remini cut 1600+ pages into under 400). They tend to simply give a recap of the events of the subjects life without much explaination or connection between events. Happily, Remini's book does not fit that stereotype. In the introduction, Remini says that he keeps in mind that this will most likely be read casually by people mildly familiar with Jackson. He therefore specifically points to events in Jackson's life and tell the reader, "this is important because later Jackson will remember this and..." He does this from the earliest days of Jackson's life; admitting that Jackson was a bully of sorts, Remini also says that he might not be so abrasive if he had the influence of his father (who died before Jackson was born) or if he didn't have to rely on charity from his uncles and aunts to survive.
Through this technique, Remini gives the reader a fuller view of Jackson and how the many circumstances of his life come together to produce a unique man. Along with the man's characteristics mentioned in the first chapter, Jackson is also extremely patriotic, devoted to the Christian religion, slightly paranoid, in constant pain from bullets lodged in his body and a refusal to let himself rest, a workaholic, and an excellent strategist.
While I do agree with some that Remini could have elaborated more with regards to certain issues (the question "Was Jackson right to attack the bank? What were the long lasting effects? Were there other options?" etc.), it was not especially necessary, considering his goal was to introduce people to Jackson's life, not so much his life and times or legacy.
In sum, this is an admirable one volume treatment of one of America's most complex United States presidents and war heroes. If you're looking for a one-volume biography of Jackson, I don't imagine you would find many better.
