I am totally hooked on this series. This book is brilliant, it has Fear, hope, friendship and loss in a very very good plot, with twists and turns and connections that are deep and revealing to sully and dez. Someone thought they could play dez, they were wrong. With some seriously dangerous and exciting caving and family support this book is the best. It will take you places that will surprise you, sorrow, happiness and deep anger, and it has a simply great ending! I can easily recommend it.
