This book’s subtitle is How to Catch Fish When There’s No Hatch to Match, which both sums it up perfectly and points out a flaw in much of the trout-fishing advice out there. Countless books and articles have been written about fishing during insect hatches, but that’s also when you’re least in need of advice. Author Tom Rosenbauer instead focuses on those many times when you get to the river and there’s no obvious course of action. His writing is clear and entertaining and, crucially, he incorporates up-to-date research, which deflates a lot of long-held fly-fishing myths. Simply put, it’s the most useful trout-fishing book I’ve ever read.
