The sprightly memoir of a biologist who, with her feet planted firmly on the ground, took to the trees in 1979. A pioneer in the ecology of forest tree canopies, Meg Lowman climbs, studies and sleeps in trees for a living. She's also a popular lecturer on trips to the Amazon and Director of Research and Conservation at Selby Botanical Gardens in Sarasota. She's remarkably frank in this engaging memoir about balancing her multiple roles as as scientist, woman, wife and mom.  (AMZ57, $13.95)
