I wanted to open a thread with the same question! My recommendation would depend on what level you are at with running and what you are looking to get out of running.
I have recently read Paula Radcliffe's book called How to Run and I found it very informative. It talks about what gear you should get, what you should eat, gives you advice on weight training, warm up, running techniques and also includes a few training plans. I used one of her training plans to train for the Marlow half marathon and I felt it was a great plan.
