I've just finished re-reading this, and it's a great read. If you've climbed to the top of the tree you have a right to the good fruit that grow there. Mark Ellyatt is clearly proud of what he has achieved, and the dives he has done are breathtaking, but what I really enjoy in this book is the disarming honesty. What I learned from this book is that everyone screws up - even the greats. But what distinguishes the great from the dead is that they admit to their mistakes and learn from them. Somehow, in this book you get a window into his soul: you can feel his fear and his elation. You can understand how dangerous his achievements are, and fully understand how someone merely diving at weekends will not be able to reach the dizzying depths that Mark has plumbed. You learn from his honesty, because you can relive his close shaves with him. It's the moments of intense fear, where lights dance before our eyes and our tongues sizzle - those are the moments when our muscle memory is programmed. It's the muscle memory that keeps us alive when everything goes wrong. Through this book you can get a taste of those experiences without gambling with your life. If you dive deep, you've almost certainly already read this at least once. If you aspire to dive deep you need a copy.
