I made the mistake of starting The Night Guest prior to trying to wind down for the evening and did not want to put this book down. The Night Guest hooked me in with Iðunn's first trip to the doctor to try and figure out why she is constantly exhausted and bruised. The initial encounter with the doctor and her the desire understand what's wrong *and* have it be easily fixable from a doctor is highly relatable as someone with a chronic illness. Similarly relatable was the results inevitably coming back normal and well meaning friends and acquaintances try to provide advice, including all of the alternative medicines and essential oils to try to fix you. 

As the mystery with Iðunn's illness unfolds, we get hints into what is going on - her fitness tracker has her at 40,000 steps and when she eventually enables the GPS, she finds she's heading to the same place each night. Along the way, we meet her married coworker and ex-lover, Stefan, her dead sister's boyfriend, and plenty of neighborhood cats. 

I really enjoyed the novel overall - it's very tightly written, and the increase in Iðunn's desperation gets more and more evident by the single line entries that we get within the book. I could feel the intensity ratchet up, and the writing was further animated by the incredible narrator of The Night Guest, Mary Robinette Kowal. Mary's ability to inhabit the emotional state of Iðunn was fantastic, and I also really appreciated having her pronunciations of Icelandic names so that I could better understand how to say everything myself. 

Thank you very much to NetGalley and Macmillan Audio for providing me an advanced copy of the audiobook.
