I loved this dystopian, psychological murder mystery written as diary entries from an unreliable narrator. The premise is fantastic; the world as it is known ends due to nuclear war, and 20 strangers are left in a hotel. It's a wonderful idea and extremely well explored. The characters are well written; they are likeable, dis-likeable, untrustworthy, mysterious, aggressive, helpful. All the characteristics I'd imagine you feel at the end of the world. It was easy to become embroiled in their struggles, and to care about their outcomes and to reconsider time and time again who to trust. The setting is very well chosen. A large, yet claustrophobic hotel with a nearby forest in Switzerland. It was so well described and so well written that i could imagine myself as one of the ragtag bunch. I could see myself in the meetings in the dining room, meandering down the long corridors and up on the roof, overlooking the trees, helping where I could. It all fed well into the story. The action in the book was exciting. I can't say too mush as I definitely don't want to give anything away, but what i will say is this; at 98% completed, there were still things happening to make me gasp. Not until the last word was read, was the story completely tied up. Definitely one to keep you breathless and on the edge of your seat! It's early in 2019, but I think that this book will almost certainly be in my top reads of the year!
