The Darth Maul one is called Shadow Hunter. To be honest...there were a few books spawned from the latest films although they're not very good and crippled by having to tie in with the events of those dire films. Having said that...the last 3 books of the Republic Commando series were not bad at all. Karen Traviss is definitely one of the better authors. Timothy Zhan still holds the crown, imo, although she'd definitely be second.
You definitely got the best one for Sith...from the novels anyway. I won't give anything away about why it's an essential read for all things Sith but it was a story that needed to be written.
