The Cottingly Secret by Hazel Gaynor is a great summer read. In 1917, cousins photographed fairies and were thrust into international fame. But did one of the cousins actually see them? One hundred years later, Olivia, whose grandfather has just died and left her his bookstore, stumbles on the cousin’s story and links it back to her own. Olivia’s tale is interesting enough on its own, but the interweaving with the historical makes it even better. While you will need some suspension of disbelief, it’s not too much to make the story unbearable.
