Dual series, needs split/renamed

http://www.librarything.com/series/Lords+of+Avalon is 2 separate series that are combined by virtue of having the same name.
If there was only normally numbered books and two authors I'd fix it myself. Two of the books I'm not seeing an obvious link for and I don't happen to be inclined enough to do the research.

If you are talking about the two anthologies at the end then these belong to the Sherrilyn Kenyon series. If you look at the first of the anthologies you can see that in bluetyson's review he lists "The Wager - Sherrilyn Kenyon and Kinley MacGregor"

Fixed, authors names have been added to their appropriate series.
