Voidwitch Saga

Mariam Xi can kill you with her mind. She escaped the MEPHISTO lab where she was raised as a psychic supersoldier, which left her with terrifying capabilities, a fierce sense of independence, a deficit of trust and an experimental pet named Seven. She’s spent her life on the run, but the boogeymen from her past are catching up with her. An encounter with a bounty hunter has left her hanging helpless in a dying spaceship, dependent on the mercy of strangers.
