There are tons of Buddhist writers. But Pema Chodron's books are the ones which sell out fast and appear dog-eared on library shelves. It's her ability to simplify the tenets of a religion which has layers of thinking that makes her so popular.
"Like spreading butter on bread" is the way a member of the New Haven, Connecticut Shambhala Center described both Chodron's thinking and writing. "It's that basic and that simple." We who attended a discussion meeting after meditation this evening nodded in agreement.
In the 10 years I have been reading and re-reading Chodron's books such as "The Wisdom of No Escape" I have learned from how she simplifies. Instead of introducing a topic through all the concepts and terminology of Buddhism she will essentially say something like: You are perfect as you are and maybe a little improvement will also be good. Everyone can understand that. And no one backs off, offended.
Here you can sample some of her stuff, for free. This contains her guidance for how to navigate difficult times.
