The story was good and enticing. I was expecting something more thrilling and fleshed out. Not much of a spine tingling story but it really could’ve been. I feel this book had a lot of potential. I don’t like how the ended is structured. It’s very short and doesn’t satisfy the build up. There is a lack of clarity with the correlation of missing cats, the dead sister, the two love interests and the things that happen when Iounn is asleep. There was potential to draw those parts of the story out. Depth and stringing the readers curiosity along is lacking. ‘The Night Guest’ has a great setup to be more. The ending suggests it’s “Her” which I am guessing is the sister. There are also areas to explore and delve deeper into. What was found under by Iounn after her sister passed? What if she did go to the psych ward and more sinister happened. Real thrill and development is missing. Disappointed with the ending.
