To DarthAvlectus, True it does have good elements. Jedi Exile is one of the weakness of the book. Revan, despite him being a supposed tactical genius, becomes a Leeroy Jeekins when fighting the Sith Emperor.
Canderous's arch was quite good with or without Revan.
In my personal opinion, Canderous's arch should be at least a book unto itself and Darth Nyriss and Scourge as a team focus on the Sith Emperor and his mysterious past.
