i LOVED this series!
I read all of them in less than a week's time.
In 4th book I had an issue with how Jon was acting, I just hated how Jon felt and talked about the grubs. I understand that it's a different time, and I can't possibly put myself in his shoes, but it just bothered me.
I couldn't image Sarah and Jon's relationship working out after what he attempted to do to her to scare her away. I couldn't just forget that and go back to someone who has been showing major issues throughout the book.
The details given were amazing. Every scene i could easily pictured in my head. Every emotion that was supposed to be felt, i felt and then some.
The end wrapped up the series well.
