I recently finished reading Americanah! It captivated me so much! One of the most emotional parts was when she decided to go "work" for that slimy man, I couldn't believe it...
I was mostly reading it while I was commuting to work, and sometimes I was just laughing out loud and people were just staring at me thinking it can't be that good!
I just started reading Half of a yellow sun! I have a feeling it's not going to interest me as much as Americanah did.
Half of a yellow sun is very beautiful. Emotional too. You'll enjoy it.
