I'm currently reading the best book I've read yet on Zen Buddhism. It is based on talks by a roshi, the late Dainin Katagiri, who came to America in the sixties to teach zen. Dainin Katagiri worked with Shunryu Suzuki at the San Francisco Zen Center for a time before Suzuki died in 1971. The book is "Each moment is the universe : Zen and the way of being time" and was published this year. The theme investigates works on "being time" by Dogen (13th century). I found a copy at the library (yay!). There are great tools in the book.
