Enigma is a wild ride.  There is lots of foreboding atmosphere, mystery, and spicy romance. I especially like the heroine, Salem. She is an interesting combination of intellect and trauma, and narrator Jaclyn Kelso does a great job of showing Salem’s internal chaos and external stoicism.  Aiden Snow is awesome, as usual. He brings all the heat and all the snark to Cas.
Also, the epigraphs that start each chapter are perfect.. The quote that kicks off the second epilogue slayed me!  Well played EuNyx, well played. 

Thank you NetGalley for providing me with a copy of the audiobook.
