I have read a number of books on Alexander the Great and finally decided to read Wilcken's biography on Alexander since it is cited in so many other works. While the book covers all the high points and is generally favorable in its treatment and view of Alexander, it fails to give any real detail about the man, his life or his military exploits. If you know little of Alexander you will find the highpoints here. If you are looking for something new, the only information that I had not seen before was the author's speculation about Alexander's future plans; and the author's discussion of the legacy of Alexander. There is an interesting discussion in the introduction about earlier Alexander biographies.
