Review of 'The Space Between Worlds' on 'Storygraph'

4 stars

Multiversal travel has been invented, but not only can it only reach the 380 worlds most closely aligned with ours, anyone who visits a world where their alternate self lives, dies painfully on arrival. 
Thus the scientists must turn to the most disadvantaged, lowest mortality people in their society to travel. Those whose odds are so stacked against them living it is a miracle they’ve survived on this world. 

Cara is dead on 372 out of 380 worlds. Her survival here is a miracle that brings her out of the gangs in the wastelands to a job in the city with the chance of citizenship. Between flirting non-stop with her distant boss, she is on a path to security. But one of her remaining doppelgangers dies mysteriously opening up another world that uncovers dangerous truths about her own.
It’s an interesting take on the multiverse trope and is a good read. It gives focus to privilege, identity and the chance of happiness..
