I haven’t read any of these, and they are not published by a major publisher – I’m not previously aware of Wives of Bath press. However, the series is listed at SYKM, and the fifth title, The CEO came DOA, was a finalist for the 2017 Lefty Award for Best Humorous Mystery. So I think they are legit. And, WTH, a box set of the first six titles is free right now at Kindle US and UK, so you can just try them to see if you like them, risk-free!
