Tides of Darkness
Tides of Darkness was a really good book. I definitely like the way Aaron Rosenberg writes better than Jeff Grub. Jeff Grub has a more dry writing style that is similar to Tolkein's writing.
This book is the third in what is considered the War Chronicles. These chronicles cover the original conflicts between the orcs and the humans. For me this series is an introduction into this story as I never played the Warcraft RTS games. I'm hoping that someday Blizzard will release an HD version of these games so I finally have the chance to play them.
