The Space Between Worlds by Micaiah Johnson SIGNED 1st Edition Illumicrate

Eccentric genius Adam Bosch has cracked the multiverse and discovered a way to travel to parallel Earths. There's just one problem: no one can visit a world where their counterpart is still alive.
Enter Cara. Of the 380 realities that have been unlocked, Cara is dead in all but 8.
Born in the wastelands outside the wealthy and walled-off Wiley City, Cara has fought her entire life just to survive. So when she's offered a job travelling the multiverse, and a safe place in the city to call home, she's willing to do anything to keep it that way.
But then one of her doppelgängers dies under mysterious circumstances, and Cara is plunged into a new world with an old secret. What she discovers will connect her past and future in ways she never could have imagined - and reveal her own role in a plot that endangers not just her Earth, but the entire multiverse.
A stunning science fiction debut, The Space Between Worlds is both a cross-dimensional adventure and a powerful examination of identity, privilege and belonging.
