Like Buddy read ?
Well, first of chalk up your likes and dislikes.
Find author you have in coomon and which book you both haven't read.
I would suggest start with something lite to read.
Try Mitch Albom's work.
And i would suggest, like read it together.
like you both can start the book at same time and read few chapter in a go.
Rest try to find what you both can enjoy, that's important, if you read something shitty, it will ruin the experience.
Best of Luck
