Day 04 - Favorite book of your favorite series
I'm not saying that The Dark Tower peaked with the third book, because the series as a whole is very strong. But this is definitely my favorite installment. I think it was watching the Ka-Tet come together, King emphasizing that fate was drawing them to each other, watching them become a family. Roland hadn't been really close to anyone (that we knew of in detail) until this book, and you see him become a friend and a father figure. It was a real step in the right direction for the character, some big development for him, and it informs the way the rest of the series plays out.
Also, some of the scariest stuff you'll see in the series happens here. Like Blaine, who is in fact a pain. And the wastelands themselves, with their mutant creatures. Shardik, the crazed robot bear. And more, but I don't want to spoil anything for the uninitiated.
Oh, and this is Oy's first book, too. Maybe that's what this is all about, my eternal love for Oy. That might be it.
