Many of Lenski's books can be collated into 'series' - but since they don't have to be read in order, you may be better off just looking for more information here: http://library.illinoisstate.edu/uniq...
Probably her most famous set is the following:
American Regional Series
Beginning with Bayou Suzette in 1943, Lois Lenski began writing a series of books which would become known as her "regional series." In the early 1940s Lenski, who suffered from periodic bouts of ill-health, was told by her doctor that she needed to spend the winter months in a warmer climate than her Connecticut home. As a result, Lenski and her husband Arthur Covey traveled south each fall. Lenski wrote in her autobiography, "On my trips south I saw the real America for the first time. I saw and learned what the word region meant as I witnessed firsthand different ways of life unlike my own. What interested me most was the way children were living" (183).
In Journey Into Childhood, Lenski wrote that she was struck by the fact that there were "plenty of books that tell how children live in Alaska, Holland, China, and Mexico, but no books at all telling about the many ways children live here in the United States"

“A new respect for Nature had been learned, a new kinship with sun and water and soil....They had learned that while Nature is often beautiful and kind, her laws must be respected, for they are ruthless and inexorable as well. Man must accept these laws and adjust his way of living to them. Then only can he prosper.”
“A hard lesson had been learned--that man himself suffers most when his hand despoils the earth and robs it of its legitimate fruits.”
“It don't matter what happens, if you're only srong and have great courage.”
