Are you reading La casa verde in Spanish? If so, your Spanish must be really good, because it's a highly expermental novel. I'm impressed!
I am a huge fan of Vargas Llosa, but I haven't read La casa verde yet, which is weird because I've read almost all of his major works. He is probably a better writer than Bryce Echenique, but Un mundo para Julius (A World for Julius) is a very unique and tender novel. I hope you enjoy it!
