Loved Harry Potter as well. Completely agree with the 3rd book of the hunger games and divergent being terrible.Anne of Green Gables. Also Harry Potter
I liked “Hunger Games”and “Divergent” but in both series book 3 ruined things for me.
I still haven’t read the “Outlander” books but need to since I love the series.
The Dark Tower by Stephen King.
The Agent Pendergast series by Douglas Preston & Lincoln Child.
That was my answer as well!James Herriott's All Creatures Great and Small series. An English veterinarian in the first half of the 1900s. PBS used to have a TV show based on it. I read through them several times as a kid.
Despite nearly derailing in the later books, I also love:
^Haven't read all of these but I do enjoy them even though they are so outlandish.
Even though it's not finished, I really like A Song of Ice and Fire.
I also have a soft spot in my heart for the Green Sky Trilogy and Xanth because that is my childhood right there.
Most recently I enjoyed the Bill Hodges Trilogy.
