Believing Christ: The Parable of the Bicycle and other Good News by Stephen E. Robinson
This is kind of a famous book in the Mormon community--probably everyone has heard the parable of the bicycle--but I don't read a lot of LDS books, so I hadn't read it until now. Its reputation is well-deserved--it's excellent. Carefully and clearly written, with plenty of scriptural support and some good stories, It's not difficult reading at all, but profound concepts are well-explained. I'm adding it to my Required Reading list (which only exists in my head, but maybe I'll write it down someday).
