Ebook: Guidebook to Mechanism in Organic Chemistry (6th Edition)

I used this book, as a visiting scholar at Oxford, and was captivated by the author's presentation of my most disliked area of Undergraduate chemistry. Peter Sykes, has accomplished a certain level of intellectual simplification evidenced in this book, that has made it enjoyable and more importantly, fluid. He does not belabor the material and his book is one of the few on the subject, that was genuinely written to be read.
I definitely recommend it.
