Sitting poolside

Finity's End is getting really good. I read this morning while my younger daughter was having a riding lesson, and now again by poolside while they both frolic. I'm currently on page 202 out of 564.
It was a bit slow at firat to get into this story, but now I'm really getting hooked. The main character, Fletcher, is on the merchant ship with his family now. He doesn't want to be there and they don't want him there either. He's working on making peace with his situation while a war story plays put in the background.
The characters are complex and believable; I can engage with them and care about what's happening with almost all of them. That's more than I can say for some books.
