This story is both entertaining, uplifting, and at times heart-breaking. Mike Chen is quickly becoming one of my favorite authors.

Mariana and Carter are such fun, engaging characters. I felt such a connection to both of them at different times in the story as they worked to solve the problem that has set them on a repeating time loop.

Memory plays a huge role in the story, both Carter’s eidetic memory and Mariana’s enhanced memory allow them to build on their work each loop. And allows them to take some adventures along the way they would never have taken without the loop (and resetting bank balances and cholesterol levels). It also allows them to grow closer. But memory is not perfect, and sometimes it can slip.

The story is told from Mariana’s point of view, so we do get a deeper look into her life and losses. But Carter shares much of himself with her, so I feel like we get a fairly deep look into his motivations as well.

I don’t want to give away too much of the story, but once the anomalies started appearing, my heart broke for them both, but especially Mariana. The story took a turn I didn’t expect, but completely welcomed. And the ending was intense. It left a lot of unanswered questions (which normally drives me crazy, but didn’t in this case), but was also very satisfying at the same time.
