Book excerpt: In dramatic narrative form, Phil Keoghan transports the reader from the Yucatan Jungle to the depths of an underwater cave to the top of an erupting volcano. But this is no armchair traveler book. It is an urgent call to action, inspiring and enabling people to overcome fear and seek out memorable experiences of their own. With his fresh and compelling N.O.W. philosophy, No Opportunity Wasted will help us all dream more freely and live more fully.
