Factual error: Error is about two thirds of the way through this book. The central male love interest is a terrifically talented high school history teacher. His wonderful, down to earth way of keeping student attention is highlighted when he talks about war between Britain and Germany and he illustrates the relevant lesson by drawing pictures on the whiteboard. These include a swastika for the Germans - shame he's giving a lesson on the first world war (1914-18), which makes the reader wonder exactly how terrifically talented and knowledgeable he really is. The swastika was adopted by the Nazi party in 1920 and incorporated into the German flag in the mid 1930s.
