The African Queen — C.S. Forester

First published in 1935, C.S. Forester's classic romantic adventure is a tale of opposites attracted. Allnut and Rose, a disreputable Cockney and an English spinster missionary, wend their way down a river in Central Africa in a rickety, asthmatic steam launch, and are gradually joined together in a mission of retaliation against the Germans. Fighting time, heat, malaria and bullets, the two have a dramatic rapprochement before the explosive ending of the book. This tale of unlikely love is thrilling and funny and ultimately satisfying.
