Pure Love is a short but intense novel that demonstrates the love between two people at a much-deeper level than normal humans love each other. Their love starts at an early age and takes them through some of their adult life. Some of the language and love is somewhat graphic, but it depicts human nature. The story starts when Betty Sue is only eight and Alan is twelve. They both lost their parents to the Spanish flu, which occurred during and just after World War I. Alan had lost his sister at that time, who he loved dearly. She was the same age as Betty Sue, and Betty has much of Alan's sister's mannerisms, which causes Alan to love her. Both are put into a satellite orphanage in Chicago. The authorities try to separate them, and they run away, starting the adventure of their lives.
