An outsider who can travel between worlds discovers a secret that threatens her new home and her fragile place in it, in a stunning sci-fi debut that’s both a cross-dimensional adventure and a powerful examination of identity, privilege, and belonging.
Multiverse travel is finally possible, but there’s just one catch: No one can visit a world where their counterpart is still alive. Enter Cara, whose parallel selves happen to be exceptionally good at dying—from disease, turf wars, or vendettas they couldn’t outrun. Cara’s life has been cut short on 372 worlds in total.
On this Earth, however, Cara has survived. Identified as an outlier and therefore a perfect candidate for multiverse travel, Cara is plucked from the dirt of the wastelands. Now she has a nice apartment on the lower levels of the wealthy and walled-off Wiley City. She works—and shamelessly flirts—with her enticing yet aloof handler, Dell, as the two women collect off-world data for the Eldridge Institute. She even occasionally leaves the city to visit her family in the wastes, though she struggles to feel at home in either place. So long as she can keep her head down and avoid trouble, Cara is on a sure path to citizenship and security.
But trouble finds Cara when one of her eight remaining doppelgängers dies under mysterious circumstances, plunging her into a new world with an old secret. What she discovers will connect her past and her future in ways she could have never imagined—and reveal her own role in a plot that endangers not just her world, but the entire multiverse.

My Review:

The Space Between Worlds is filled with paradox and wonder, and resonates to the beat of butterfly wings.

This is a story of the multiverse, of parallel universes that are almost, but not quite, the same. Universes that are all post-apocalyptic, in one way, or another, or all of the above.

It’s also a story of irony, in that this is a story where the people that society has classed as the most expendable, are also the most valuable – but only as long as they are useful.

And it’s a story about families, and the infinitesimally thin line between love and hate.

The Space Between Worlds is a story about contrasts. The contrast between safe, wealthy and white Wiley City, and the dangerous, poor and brown wastelands that surround it.

Cara is someone who walks between the worlds. Because she is a wastelander, brown and disposable on seemingly all of the worlds that resonate enough with “Earth Zero” to be visited, she is mostly dead.

Not in The Princess Bride sense of “mostly dead”, but in the sense that most of the different Caras, the Cara on most of the 382 worlds that are close enough to her own to be able to be visited, Cara has not lived to reach adulthood. Or at least not reached the age that the Cara on Earth Zero has.

That paradoxically makes Cara a very valuable “traverser”, or traveler between the worlds. People can only visit worlds where their local equivalent has already died – and Cara has died nearly everywhere.

But she’s also someone who travels between worlds on her own world. At work, she does her best to fit into the sterile, safe, white world of Wiley City – no matter how little it looks as if she belongs there.

When she goes back home to the wastes, she pretends to still fit into her family, the religion that keeps them together and the violence that surrounds them.

But Cara belongs in neither place. Because she is not the Cara that the Eldridge Institute hired, and she is not the Cara raised by the family she has come to love. She is the Cara from another Earth who found the original Cara dead and took her place.

Because she is a survivor. It’s what she does best. It’s who she is.

This story puts that survival instinct to the test. Not just because she finds a world that she has a chance to save, but because saving Earth 175 gives her the tools to save the Earth she has made her own. If she is willing to take them up.

If she is willing to risk her safety, her secrets and her skin to discover exactly what she’s made of. If she’s willing to die to make things right, just once.

Escape Rating A+: This was awesome. A lot of my reading buddies recommended this one, and now I know why. It tells a fantastic story and there’s so much packed into it if you want to go hunting for all the possibilities, but the story has the reader on the edge of their seat for the whole ride.

The Space Between Worlds is very much a post-apocalyptic story. But it’s not the immediate aftermath. While those are fascinating because there’s so much chaos, it’s every bit as interesting to see what humans have made of the messed up world that other humans caused and left behind. Usually by dying.

One thing that caught me was that we don’t know where, relative to our current world, Wiley City and its surrounding wastelands are. And it doesn’t matter. What we see feels plausible, that enough of a city survived that it became prosperous again and gathered refugees around it who wanted to share in that prosperity and safety. Only to discover that the prejudices of the old world continued in the new. There are always haves, and there are always have nots who hope to become haves. And that the haves guard their position ruthlessly.

It’s very explicit in this story that the haves are white. Very, very white. Not just by skin color, although that seems to have been at the heart and the start of it, but also because of that ruthless guarding of privilege. Citizens of Wiley City live in a completely enclosed world. They don’t see the sun, they only experience natural light through extreme filters, because natural light can be dangerous. So over the generations their coloring has become lighter and paler.

The wastelands are exposed to all the elements. The brutal sun, the chemically destroyed earth, water and air. The dirt. They are brown of skin, dark of hair and eye, and their clothes are never completely clean because there is so much junk in the air and water.

One of the fascinating contrasts is the way that Wiley City takes care of its people, while the wastelands force their people to survive if they can and die if they can’t. At the same time, the two areas are trapped in an entirely symbiotic relationship, and they need each other.

And they are both ruled by an emperor, even if the “emperor” of Wiley City isn’t called that. And even if, in some of the Earths of the multiverse, the positions of the two rulers is reversed. Because in all of them they are brothers.

As fascinating as everything about this future world is, at its heart it is always Cara’s story. Caralee from Earth 22, who pretends to be Caramenta from Earth Zero but who only begins to figure out who she really is and what she really wants to be when she meets the one person she should never be able to meet, her doppelganger on Earth 175. They’ve all made different mistakes, the wings of the butterfly have flapped and blown them in slightly different directions, but their lives have all been wrapped around the same family and the same men, the two emperors.

But this time is going to be different, because Cara isn’t just going to survive, she’s going to fight. Once she figures out who and what she is really fighting for – and against.

This is, in the end, a story about choosing your battles, finding your path, and figuring out which version of your life is the one you can live with. And it’s awesome.
