Atoms Never Touch by Micha Cárdenas

Fierce, poignant sci-fi, about hacking, love, and resistance. 
Jumping to alternate realities sounds great, if you're in control. But what if you're not? What if you're propelled away from the people and places you love the most in the blink of an eye? And what if these involuntary journeys happen because your neurochemistry is different, and your brain works differently?
Beautiful, compassionate, and resourceful as she is, this is Rea's problem. A latina trans woman and an academic, she is beloved by a tight circle of friends, who fully accept her without knowing the cause of her disappearances. But she is haunted by the lovers and family that she cannot trace back to, and fears she might be separated from them forever.
