The book already begins very interesting with the self-made billionaire letting the reader know how family and life conditions look like for a rich person at the end of his life.
As his children only ever received money but no love from their father, they developped a materialistic world view, throwing the given money out of the window, earning no penny by own work ever.
Contrary to them stands the illegitimate daughter Rachel Lane, who has given her life to God and therefore has no interest in money. Isn't that understandable, after having lived and worked with a primitive tribe of indians in the deepest jungle of Brazil for over 20 years, happily?
As the author tells about the search of Rachel and the proceedings in court, i.e. the work of the lawyers with their clients who hope for most of the money, you can see the contraries very clearly:
On one side there is the adventure of Nate, forcing his way through the patanal,searching for Rachel, escaping from deadly situations several times. In my eyes, these are the most exciting parts of the novel! Then and again you find yourself back the huge cities of Washington D.C., where time flies three times faster than in the southern hemisphere.
The reader gets a little view from a lawyer's hectic life, a view of a billionaires childrens values and the complicated fights about the contents of a, finally, surprising testament.
In conclusion, Grisham combines (modern) life, problems, values, belief and love in an extremely good way which makes this novel to an excellent, worth-reading book.
