I should not exist.But I do.Like everyone else, Eva and Addie were born sharing a body—two souls woven together. But as they grew, the whispers began. Why aren't they settling? What if they end up as a hybrid? Finally, Addie was pronounced healthy and Eva was declared gone. Except, she wasn't. . . .For the past three years, Eva has clung to the remnants of her life, trapped in a body she can no longer control—until two other hybrids learn her secret and offer her a way to move again. When the teens are caught, they are shipped off to a remote facility determined to stamp out the recessive souls . . . permanently. Eva and Addie must escape before they lose each other forever.
