"The Power Of The Dog" Trilogy by Don Winslow. One of the most intense books I have read. Makes you rethink the war on drugs.

"Islamic Fascism" by Hamed Adbel-Samad. Written by an Islamic scholar who studied at the American University in Cairo. Debunks a lot of myths that are hijacked by fundamentalists and extremists. Makes you think about religion in general.

If you need something for the better half:
"The Murmur of Bees" by Sofia Segovia
"Tell Me Who I Am" by Julia Navarro
