The Key of Astrea

Jenny Tripper will die an early death because of a family curse that has already claimed her mother. She lives and works in her aunt's failing fortune-telling shop, and is haunted every moment by a medieval ghost.

But then a mysterious package arrives on her doorstep: a holographic woman pleads for Jenny's help in saving the Solar System from a powerful interstellar foe. She agrees and finds not only friends, doors to other universes, and the power to manipulate quantum waves, but an incredible destiny that's been waiting for her ... if Jenny can master her abilities without going insane.
