Set sometime between the French and Indian War and the American Revolutionary War, Wieland details the horrible events that befall Clara Wieland and her brother Theodore's family. Clara and Theodore's father was a German immigrant who founded his own religion; he came to America just before the American Revolution with the conviction to spread his religion to the indigenous people. When he fails at this task, he believes he has also failed his deity. One night, as he worships in his bare, reclusive temple, he seems to spontaneously combust, after which his health rapidly deteriorates and he dies. His children inherit his property, which is divided equally between them. Theodore marries their childhood friend, Catharine Pleyel, and they have four children.
