So far they're pretty great. Mercy T. is slower paced, but there are nine books so I know it will pick up soon. I read multiple books at once, :P As for manga, I haven't read a whole lot of that in recent years. I tried to pick up a couple of them and only finished Lovely Complex.
Wow, looks like I gotta add some more books to my "to read" list :D
By any chance, have you read the Earthsea series by Ursula le Guin? I have heard that they are amazing!
