Most of what I am reading now is not specific to MLC, but more about communication in relationships and insights into gender differences in how we think/feel etc.
I read both DB and DR.
I am nearly done with "The Solo Partner" which is really good for focusing on your personal reactivity. Identifying the triggers that might set you off in a relationship, learning to work around them effectively so you can maintain emotional control. There is also a helpful section on the Pursuer/Distancer dynamic in relationships.
I am concurrently reading "Men are from Mars, Women are from Venus". Lots of good insights into how when you do thing you *think* are supportive of your man, he gets a different message. I kind of dislike the writing style, but the content itself is useful.
I have a similar book called "For Women Only" which was recommended to me by several DBers. I haven't started reading it yet.
I also have read several of the Andrew Marshall books... "I love you but I'm not in love with you", "Resolve your differences", Love yourself enough, "Help Your Partner Say Yes" <-- Admittedly a couple of these books with "7 steps to..." in the last half the title have some overlap in the content. Those 7 steps sure are handy.
