I'm reading a lot of historical mystery series now because I'm working in this genre which is new to me and I've bought several first books of series either for free or for a very cheap price. (buildbookbuzz.com)
I thought of the opening to Swallows and Amazons, the first book of the series. (firstthings.com)
In Left Behind, the first book of the series, Steele's wife, Irene, leaves only her nightgown and her open Bible behind in a rapture that occurs while he is away on the job, flirting with another woman. (religion-online.org)
