i liked peace talks a lot - i see a lot of complaints on amazon reviews, but for me, it was very entertaining and brought us back some of our favorite characters.
i also really enjoyed half of battle ground - the first half - and a little of the ending, but unsurprisingly (considering the title), there was too much battle description for my taste in the second half - not bad for what it was, but not my favorite thing.
oh, and the audible version of battle ground comes with a christmas short story that's funny, fun and a little heart warming
