As a therapist working with many adults with ADHD I highly recommend this book. It is one of the most helpful books on the market written specifically for the individual coping with ADHD. It can be used as a reference book but also lends itself to being read cover to cover over time, after which the reader can refer to it as a helpful reference. Also have it on Kindle though I recommend purchasing the paperback as well. With the paperback it is easier to use when wanting to refer to different parts of the book quickly.
