Dude, MS, I love Warriors!!
Being a part of the Warriors fandom is how I actually came up with my screen name
I really loved the books. But I only got as far as the first book in "The Fourth Apprentice" series.
Uh... Any others, let's see... I really liked the Percy Jackson series. Lots of really good fleshed out characters, and a great overarching story.
Oh! The May Bird series. Loved it. Really thick, all 3 books. But damn, the lore is great. The characters are believable, and the story can be heart wrenching at times.
And my most favorite series of all time, The Skinjacker Trilogy. An amazing series. The characters are phenomal, and the books age with the audience. The prose becoming more mature and developed as the story continues. The back stories of the kids are rough, and even if they are despicable people in the afterlife, you sympathize with them. There are reasons for why they do things. And the way the world is described to work, unf! It's such a good series. I really have nothing but praises to sing about the series.
