The first cycle is mainly Jill and Rhodry's relationship with Nevyn's involvement and the past life stories are all of Nevyn's involvement with them (the only series where he exists in the present). This is the best series by far.
The second is set 40 years on (and spans about 20 years) in the present and is mainly about Dallandra and Evander's attempts to have the Guardian race born as creatures of flesh. Rhodry features a lot but Jill is much lower profile. The past life stories are about them and Aderyn, Rhodry's past, the end of the 100 years civil war and one about Jill and Rhodry during the first series. (This is my least favourite series, I'm not a fan of Dallandra and I don't care about Evander.)
The third has more about the original humans in Deverry, the escaped bondsmen at Cerr Cawnen, and goes into more detail about the horsekin and the gael de thea. The past lives are mainly about the end of the civil war. (I preferred this series to the second.)
The fourth series is about Branna, Neb and Rori. Or at least it's supposed to be. The first book certainly makes it seem that way, unfortunately there is way too much Dallandra at all the other characters' expense. The past lives are a bit muddled, imo. One in particular seemed too much of an unnecessary retcon (the Morwen and Gwairyc one). My other main problem is that I really wanted to experience more of Spoiler: Nevyn/Neb and Jill/Branna as a couple. I wanted to see what happened with Jill and Nevyn after she apprenticed to him, so we could see why she comes to love him. And I wanted to see more of their love as Neb and Branna then we do because as far as we've seen so far Rhodry is her true love not Nevyn. As it was the last past life sequence shows us another Jill/Rhodry love story, set even before the events that set the whole story in motion.
