Mercifully brief, this is a great little book written by an American anesthesiologist. You won’t finder a better description of core physiological principles in any of the recommended texts. There are also cool little puzzles at the end of each chapter which I found strangely appealing. The chapter on cerebral perfusion pressure including a discussion of the applied physiology in the giraffe is a real highlight. In fact this is the book you should read first before embarking on Nunn et al.
