I've recently finished The Year of Living Biblically: One Man's Humble Quest to Follow the Bible as Literally as Possible by A.J. Jacobs.
I loved it. Jacobs is a witty and honest writer. It is a wonderful memoir of his spiritual journey. He writes as a "nominal Jew," meaning that he is Jewish by birth but isn't active in the faith. My favorite aspect of the book was "watching" his openness to the Jewish (and to an extent even to Christianity) faith and how it began to change his agnosticism--at least in bits and spurts. It was beautiful to see how he embraced his heritage and the change it made in his life.
As a huge bonus, Jacobs is hilarious! He shares his struggles as a father and a husband, and even as a son. I don't want to ruin anything but the word "helmet" will forever make me laugh any time I hear it. One of my favorite parts of the book is when he attempts a stoning. As a little preview, check out this picture (if you click on it, it should enlarge). If all of this doesn't convince you to check out the book, I don't know what will.
It's a wonderful read. I hope you'll check it out and enjoy it as well.
