Epistolary novel. A pretty easy read. It is a story of how an accidental email turned into a pretty intense emotional affair. Was it a romance? Was it a warning that the line between flirtation and “too far” is invisible? Was it an invitation to look outside of one‘s bubble? To reassess a longterm relationship? I can‘t tell yet. The ending was logical. Apparently there is a sequel, I don‘t know if I care enough to read it.
