Need recommendations

I decided to start a 101 Things in 1001 Days challenge. You can read my blog about it here.I have three reading challenges, two of which I could use some help.

 

The first challenge is to read 20 books recommended by other people. Namely, you guys. So please give me your recommendations and I will try to incorporate in my challenge.

 

The second challenge is that I am planning on reading one non fiction book a month during the challenge, so I am also looking for some good non fiction reads to use during the challenge. 

 

So let's hear your recommendations...and GO!
