The Body Language of Love | 
One of the best books I've read devoted to relations. It helps to understand more and mitigate hard times in moments of the storm between man and woman.
Main insights:
- system of signals to deliver signals to your future spouse.
- body language to use or avoid based on the purpose you have.
- concept of idea relations (how to build not broke).
I wish I had this knowledge few years ago. Definitely, worth of time and easy to read.
