I am very interested with the Diablo lore, so I decided to order the Sin Wars Trilogy after reading about how those are the first three books one should read. After I read those books, in what order should I read the rest?

I've read the Legacy of Blood book when i was maybe 11. Either i was too young to comprehend what was going on or it was a really boring read.

The Diablo Wiki isn't too bad if you want to find out more about lore.
