Book excerpt: Before The Perfect Storm, before In the Heart of the Sea, Steven Callahan’s dramatic tale of survival at sea was on the New York Times bestseller list for more than thirty-six weeks. In some ways the model for the new wave of adventure books, Adrift is an undeniable seafaring classic, a riveting firsthand account by the only man known to have survived more than a month alone at sea, fighting for his life in an inflatable raft after his small sloop capsized only six days out. “Utterly absorbing” (Newsweek), Adrift is a must-have for any adventure library.
