An interesting story that could have been extraordinary if the world-building had more depth.

I initially discovered this book when I saw some fanart of Cara and Dell, and on that front the book did not disappoint. The main character whose first perspective we experience is Cara, who works as a traverser. A scientist called Adam Bosch discovered the existence of the multiverse and found a way to travel to parallel worlds that are all different from Earth Zero. But to travel to another version of our planet, the person must be dead in the alternate universe already, or you die when traversing to it. Cara is special, because of the known alternate Earths, she is dead on all but 8, which means she has more access than any other traverser.

On a trip to Earth 175, she discovers a sinister truth though, that changes everything about how Cara views traversing.

Very cool concept, but as I said above, very weak on the world-building. We only get to experience a bit of the city Wiley, and the slums outside of it called Ashtown. It felt a bit Mad Max style, but we do not get more info than that. This is a bit disappointing. The rest was captivating though, so I still thoroughly enjoyed myself.
