Overall I found this book tedious and disappointing. With a "groundhog day"-esque feel, Aiden is repeatedly tasked with discovering who murdered Evelyn Hardcastle. Each day, he awakes as a different individual that had something to do with Miss Hardcastle's death or is able to provide him with a new perspective. He is doomed to repeat this task until he is able to find the killer. This was a complicated read and one which required absolute attention, though I often found myself uninterested and my mind wandering to other things. Even with the conclusion, I felt unsatisfied and was left with too many unanswered questions. Generally, I was ready for the book to be over and when it finally was, I found myself asking "but why do I care"? Well written and unique, but ultimately not one I would recommend.
