Books like The Ships of Earth

I described Book 1 of this series as a sci-fi fantasy blend with interesting worldbuilding and characters. Unfortunately from there it seems to have gone downhill for me.Book 2 was different, with a few additional interesting characters and a quick read, but book 3 from the start was slower paced, and had a smaller cast of characters. The same characters again and again grew draining, but I persisted, hoping the story might pick up.It didn't. Sure the characters got from location A to location B with some emotional journey in between (including birthing many children who really didn't have much impact on anything) but it all felt like a waste of time when it was known from the start that it's destination C (or perhaps D) that they're really after. And it was clear they were going to get nowhere close.Rather than giving up entirely, I still progressed slowly through this book and I intend to finish the series if it doesn't get even slower from here. I'll just have to wait (and then wait some more) and see.
