Another good one:
The Perfect Wife by JP Delaney, narrated by Saskia Maarleveld (one of my favorite narrators), Graham Halstead, and Euan Morton.
This is being marketed as psychological suspense, which it definitely is--a riff on a basic amnesia plot--but the blurbs skirt around an element that puts a unique twist on that plot (revealed in the first few pages, but I'll use spoiler tags anyway).
Enjoyable and interesting on many levels; definitely would put this in my top ten for the year.
