Rainbow Gap by Lee Lynch

Jaudon Vicker and Berry Garland are polar opposites yet know they are meant to be together. Growing up in steamy backcountry Central Florida, they fight each other's battles: Berry protects boyish Jaudon from bullies, Jaudon gives the abandoned Berry roots. They pledge that nothing will part them, not a changing Florida nor a changing America, not Berry's quest for her spiritual path, nor Jaudon's ambition for her family's business. When the war in Vietnam, politics, police, rough times, society itself, and other women threaten to come between them, their bond grows deeper. In the safety of their secluded tree house hideaway, they learn to dream, dance--and to make love.
