You really don't think you are going through a midlife crisis until you come to a realization. Without meaning to, you have started reading three separate novels, which is not something you normally do. You have sort of forgetten, through circumstance, about the last one you started.
However, the novels in question are good ones, if first impressions are any indication. I speak of Gemma Files' Experimental Film, Stephen King's Doctor Sleep, his sequel to The Shining, and Jeffrey Round's After The Horses, his newest Dan Sharp mystery, which falls on your reading shoulders like an old coat that you want to esnure still fits.
Hey - as for as dealing with midlife, there are worse ways to cope.
