Coco is left all alone in New York City at the end of the world. All around her, people are trapped in their own individual loops of time, endlessly repeating the same tasks that they were doing when the end of the world began. Coco scavenges for food while trying to avoid the "loopers", knowing from sad experience that if she disturbs their time loop they will die. After years of solitude, Coco begins to wonder if there might be others like her out in the world, people free from time loops. She charts a way to navigate the spaces between time loops and decides to leave New York.

This book broke my brain! And broke my heart too. I was hooked from the very first page, and it was a wild rollercoaster of emotions right up to the last page.

The characters feel so real and intense that it tugs at your heartstrings. They go through some terrible ordeals, but it is interspersed with joy and laughter as well. I loved Coco's character! She is so fierce and sensitive and tough and caring and generous. It was fascinating seeing how she interacted with the world around her, rising to meet each challenge and growing and changing. The book spans about 38 years, so we get to see her grow into a completely different person from the scared little girl who found herself alone surrounded by time loops.

I was really interested to see how the world-building kept growing. We start out with a very small view of the world; just one person. Then the world keeps expanding and getting bigger with more and more mysteries and problems and new characters. The science fiction part of the time loops really kept me wondering and guessing.

The writing was so brilliant at giving us the big picture of the whole world ending, but also taking time to notice the little details of these people's lives, like their dirty socks or how good a cool glass of water tastes on a hot day. The stakes feel even bigger, because we stop to appreciate all the little human things that make life worth living. The end of the world is somehow even more epic when you have a quiet moment to be grateful for each breath.

I really loved that a lot of deep themes are explored in this book. The characters have to make some very tough decisions at times. They suffer and sacrifice and have terrible regrets, but that just makes them cling tightly to their families. It makes them kinder and wiser. This book is so full of hope and love! The characters ponder some deep questions as they face the end of the world, discovering what it is that makes life truly precious.

Before reading the book, I asked the marketing team if there was a lot of profanity in the book. They said it was only a little, so I accepted the book for review. It was not a little. It was a lot. (I guess those descriptors are relative. What is a lot for one person is a little for someone else.) For me, it was a lot. But by that point, I was so hooked on the story, I just HAD to keep reading, despite my discomfort at all the bad words. If it were not for that, this would easily have been a five-star book.

There are four side characters who are gay/lesbian, but they are barely mentioned. They only have a couple of paragraphs in the entire book. The lesbian couple mentions wanting to adopt a child, and a few chapters later we learn that they have adopted.

The narrative structure was unlike anything I have ever seen. It was told in four big sections alternating between two different characters, Coco and Forrest. And within their sections we get first-person excerpts from their diaries, and then chapters with a third-person narrator focusing on that character's experiences. So the narration not only kept jumping between character POVS, but also between first and third person. The diary parts were usually in past tense, and the third-person chapters were in present tense. Just wow. The style was jumping around a lot. And yet, it felt cohesive and intentional and very well done. I don't know how the author managed to tell a coherent story with all of that back and forth, but they pulled it off! Head hopping is one of my pet peeves, and I don't care for present tense, but I appreciated that it was well-organized and everything was consistent within that system.

This is definitely one of those books where you keep thinking about it for days or even weeks after you have finished reading. I keep thinking about particular scenes and bits of meaningful dialogue. I actually had a dream about it last night, because my head is just so completely immersed in this story!
