What is your least favorite book?

I think it's the Lost Hero as i don't really like Jason and Piper, many characters were ooc which is understandable and i am pretty sure PERCY WASN'T EVEN SHOWN IN THE BOOK JUST MENTIONED.

If i had to choose i would choose the sea of monsters and then the lost hero.

They're in a super big hurry, but they stop to rest at every chair they see. Then they happen to make it back in half an hour. It's like that in a lot of the books. Takes them days and days to get there, then get back to base in no time at all. It was especially bad in that book and I just couldnt take it.

Breaking Dawn Part 1 AND 2 this Book CHANGED MY LIFE I LOVE YOU S M

Sea if monsters it got boring @ times

Personally, I love all the books. But I'd be lying if I said I haven't put any thought in this question in the past. The Sea Of Monsters is honestly my least favorite of the PJO series. It was too short in my opinion and it seemed more like a bridge than anything.

I love all of the books but I went to my aunts house this past summer and I brought only 4 books with me and one of them was the battle of the labyrinth I reread that book so many times I was just sick of it so for right now my least favorite is: the battle of the labyrinth

The Lost Hero, since Jason is too perfect and Piper is whiny and annoying. I guess I'm just against those two, and that's why I hate the book.
