A clever, funny, time bending mystery. This started with a protagonist that I didn't like and reminded me of all the worst people I knew but as the story unravelled and we began to see the loops and information reveals I became invested in the solution and Vivian's survival.
The quote about similarity to Russian Doll is only in concept and this made me laugh repeatedly at the conversations and very blinkered viewpoint (at times) of our dear Viv. Recommended reading for those who like a Groundhog Day mystery.
