When I was a teenager, I loved Diane Ackerman. When I was older, I was a little embarrassed about my earlier passion for her purple prose. Her appeal is that she mixes science and reason with wonder delight (see the title). In her own words, "life doesn't require you to choose between reason and awe, or between clear-headed analysis and a rapturous sense of wonder. A balanced life includes both (p 109)." She describes a year in her garden (which sounds lovely), with discursions on the biology of the various flora and fauna.
The book is divided into four parts, one for each season, and each part is divided into many short chapters, really short essays. The best essays are great. I especially enjoyed one on grey squirrels. Others have really lovely language, like "for months snow ruled, four or five feet of it, drifting like egg whites over the garden. But a gentle thaw settled in on Monday, and all week I've heard its sinusy drip through the gutters, watched snow vanishing like cream (p 241)."
Other essays are disjointed, like listening to your friend with ADD who is unable to finish a story. Her essay on the world's great bat expert felt especially full of odd non sequiturs, more about her own emotional quirks than on the glories of the natural world. Personally, I don't have a lot of patience for that. I would recommend someone read this like a book of poetry; don't feel compelled to read every piece.
