My Review

4.5/5 stars
Perfect for your fall TBR especially if you like a little paranormal mixed with your historical mysteries.

I’ve been reading Sara Ackerman since her WWII historical fiction days (Radar Girls is still a favorite of mine), and I love the direction she’s taken with these dual-timeline mysteries. The Guest in Room 120 feels like a perfect evolution of her work: history rooted in Hawaii, layered with suspense and emotional depth.

The pacing kept me hooked, the characters were easy to root for (and fear for), and the paranormal elements added just the right amount of spookiness without tipping into full-on fantasy. If you enjoy stories that balance real history with imaginative mystery, this one’s for you.

What I Loved

The dual timeline structure: Both the 1905 and 2005 storylines are equally compelling, something rare in dual-timeline novels. The historical sections set up the eerie mystery, while the modern timeline reopens the case in a fresh, page-turning way.

The setting: Ackerman is known for her evocative Hawaiian settings, and she nails it again here. From the elegance of the Moana Hotel to the storm-lashed shores, the atmosphere adds an immersive, gothic vibe.

The genre mash-up: This isn’t just historical fiction it’s part thriller, part paranormal mystery, and even has touches of romance. I especially enjoyed the meta twist of having two writers at a writers’ conference trying to piece the mystery together.

Inspired by real history: The book draws from the real-life mysterious death of Jane Stanford in 1905, one of America’s strangest unsolved cases. That nugget of truth makes the novel even more chilling.

Final Thoughts

The Guest in Room 120 is perfect for fans of:

  • Dual-timeline historical fiction
  • Mysterious real-life deaths and unsolved cases
  • Gothic settings with a paranormal twist
  • Slow-burn suspense with a dash of romance

Another atmospheric, compelling read from Sara Ackerman and proof that Hawaii is just as rich a setting for gothic suspense as it is for WWII fiction.
