The Space Between Worlds

The many worlds hypothesis is an exciting place to start a story concept - that is exactly where Micaiah Johnson begins with The Space Between Worlds. Cara, our protagonist, is a traveler. Someone who is able to travel safely between worlds. The key requirement for a traveler is that they be dead on the world they are travelling to - a nice way of getting around some of the paradoxes that the many worlds theory has. In the world of this book, there are 380 worlds that are similar enough to the datum Earth for people to travel to. Cara is dead on 372 of them. Cara also has a secret. She may not be who everyone thinks she is.

The semi post-apocalyptic setting creates for an interesting world and subset of worlds for things to occur over. The interaction between the various worlds is carefully explored and the main protagonists are developed in interesting ways. The relationships are well developed and add some real color to the story. From the abusive relationship of Cara's former partner (which clouds her view towards him on all other worlds) to the strange and sinister manipulations of the corporation that employs her to travel between worlds, these are all fascinating a at times brutally real. The most heartbreaking is reserved for her relationships with her coworkers, both her mentor and her handler.

This book is the best take on the many worlds idea I have read so far. Thoroughly engrossing and a highly recommended read
