*4.5 stars*

This was so good. It had great main characters that had a ton of chemistry and the tension between them was incredible. It was a really sweet romance, particularly, their interactions in the past. I loved the time travel element, it kept me engaged the entire time wondering when the hero was going to find out and what was going to happen. I also appreciated the journey that the heroine goes through dealing with her grief and deciding what she wants to do with her life. The only reason this doesn't get 5 stars is that I wish the main couple had more moments together in the present timeline.
