Is there any book/resource which explain the general idea of the proof of Fermat's last theorem? I look for a book/resource which display the general idea of the proof of Fermat last theorem in a simple manner for the public.
I mean, books which is not for mathematicians but for the general public. Books like:

Gödel's Theorem: An Incomplete Guide to Its Use and Abuse by Torkel Franzén

Do anyone now any books of this kind? Also, articles or any resources are good.

Perhaps the closest thing is this article:

"A marvelous proof", by Fernando Gouvêa,
The American Mathematical Monthly, 101 (3), March 1994, pp. 203–222. 

This article got the MAA Lester R. Ford Award in 1995.
This and other papers (with various degrees of difficulty) can be found at Bluff your way in Fermat's Last Theorem.
