The Dragon Reborn
This ss the first book,where the focus is not Rand Al'thor, the Dragon Reborn. The focus is more on Perrin Aybara & Mat Couthon, as well as the girls. It's the first book where Mat really starts to shine and we start to understand his personality.
The ending reveals and clarifies a lot of things, like howcome Belzamon keeps coming back. As the title indicates this is the book where Rand, will also accept that he is the Dragon Reborn.
