Overall, a decent read. The set up worked well with letters coming from a dead wife, filling in details, showing how much love was between them. Then the mystery started. Along with the mystery came Luke's doubt. It unnerved me how Luke could doubt his wife so easily. Many questions needed answering. The author was kind enough to answer them all. The big secret, wasn't revealed until the last 20 pages or so, I sort of guessed some of it, but the magnitude of it was much more extreme. My biggest issue, too much going on at the end. It was like the author threw everything in except for the kitchen sink.
