The Two Mrs. Abbotts is the third book in the Miss Buncle Series. It re-visits several favorite characters and presents a few new ones. Jerry Abbott, who was introduced in Book Two is the main character and Barbara Buncle (from Book One) pops in occasionally.
The story takes place in 1942. Jerry's husband, Sam, is off to war and she and her friends are doing the best they can with the food shortages and child evacuees from London. There are no big adventures, just normal people coping and helping one another, which makes it a cozy book.
Though Stevenson is listed at Wikipedia as an author of romantic novels, that's not entirely true. She wrote books that were realistic with a little romance thrown in. In fact, one of the fun themes of this book is the silliness of romance novels.
Though not a Christian book, The Two Mrs. Abbotts has lovely biblical allusions that show that Stevenson was probably brought up listening to the Bible. Some of these were quite funny like when the military move into their house and Jerry and Markie are limited to the sitting rooom where "they live and move and have their being."
Good writing, biblical allusions, references to life on the homefront during WWII, and memorable characters make this another favorite of 2015.
