Rivers, on a long view, are alive. They are born; they change; they shift their channels; they forge new routes to the sea; they move both gradually and violently; they can teem (usually) with life; they may die a quasi-natural death; they are frequently maimed and even murdered. It is the annual flood pulse—the brief time when the river occupies the floodplain—that gives a river its vitality, but it is human engineering that kills it, suppressing the flood pulse with dams, irrigation, siltation, dikes, and levees.

Under the Sea Wind is a classic wilderness adventure to which all nature writing is compared. The hero of Under the Sea Wind is soon seen to be life itself, that quicksilver prize granted, for a brief time only, to the clever and the fortunate.

Paddling a canoe into the sunrise. Watching a child take her first kayak ride with her father. Dodging campfire smoke while burning marshmallows and telling scary stories to wide-eyed kids. These are some of the moments and memories depicted in Summers at the Lake. The essays—often humorous, sometimes tinged with a sweet melancholy—celebrate the people and events marking the progress of the seasons, from the budding of the first leaves of May to their falling, gold and scarlet, in September. These prose poems capture the joy of simple, lakeside living and quiet reflection.

It is hard to imagine that the busy townscape of South London was once a great wood, stretching almost seven miles from Croydon to Deptford or that, scattered through the suburbs, from Dulwich to Norwood, a number of oak woodlands have survived since before the Norman Conquest. These woods were intensively managed for a thousand years, providing timber for construction, furniture and shipbuilding, and charcoal for London's blacksmiths, kilns and bakeries. Now they afford important green space, a vital habitat for small mammals, birds and insects.

The Fishing Life is an entertaining anthology of fishing anecdotes and well-researched articles from across Paul Schullery’s research and fishing career. The author offers up stories, essays, farces, daydreams, and ruminations that will engage listeners of all kinds. Of course, being a fisherman and living the fishing life goes beyond just those days spent with rod and reel in hand. It is something that occupies your mind and your heart, not just your hands.

Traditionally, Americans learned in school that the ancestors of the people who inhabited the Western Hemisphere at the time of Columbus' landing had crossed the Bering Strait 12,000 years ago; existed mainly in small nomadic bands; and lived so lightly on the land that the Americas were, for all practical purposes, still a vast wilderness. But as Charles C. Mann now makes clear, archaeologists and anthropologists have spent the last 30 years proving these and many other long-held assumptions wrong.

In Rivers of Power, Geographer Laurence C. Smith tells the sweeping story of rivers and how they made us. Rivers have opened frontiers, defined borders, supported trade, generated energy and fed billions. Most of our greatest cities stand on river banks or deltas, and our quest for mastery has spurred staggering advances in engineering, science and law. Rivers and their topographic divides have shaped the territories of nations and the migration of peoples, and yet - as their resources become ever more precious - can foster cooperation even among enemy states.
