I very much enjoyed this book. It was recommended on the XOXO slack, and worth the recommendation.
The premise is that the multidimensional universe exists, which means resources on one universe instance can be harvested for the prime planet, the first planet to develop the technology to traverse between worlds. The catch in this traversing is that only one instance of a person can exist in a universe. If a traverser, a walker between universes, arrives in a universe where their counterpart is still alive, then both die. Which is to say, the most valuable traversers are those who are alive on the prime Earth, and dead in all the other universes.
The story is told from the point of view of Cara, a traverser who doesn't quite belong on the Prime.
Yes, all sorts of spoilers:
The original Cara went to the narrator Cara's world and died, because duplicates can't exist (see above). Cara, being the survivor that she is, assumed Prime Cara's identity, and travelled back to Prime. So, now we have Cara figuring out what is going one, an uncomfortable longing, a world of comparable riches, new social dynamics to learn even as the universes are quite parallel, and a confrontation to power. The ending is not the typical happy ending, but isn't isn't an unhappy ending, more of a "yeah, that's the right ending."
The book, similar to Dread Nation in its character and voice, is engrossing the whole way through. Recommended. Good science fiction and worth the read.
Because no traverser has ever made a report to enforcement or asked questions, they think they’ve pulled this elaborate ruse on lower-level employees. But really, we just don’t care. A job’s a job, and people edging out other people to make money buying and selling something invisible just sounds like rich-people problems.
