The Wing Feather Saga Series

Don't think of this as a children's series and don't let that stop you from reading it because I did not have that thought at all as I was reading it. In terms of age group I would recommend ten years old and up but yeah do read the physical books. The four books are 1,422 pages that took me 36 hours and 19 minutes over 22 days to get through. It averages 61 pages per day so for more pleasure read it to your children.
