No Longer Aliens

Take a little nap for 100 years and everything changes!
Tiana's been marooned on Earth for centuries. She can barely manage to pass for human, but she's tracked a band of planet-wasting monsters here from across the galaxy and hasn't accounted for all of them yet. When she awakens from an unexpected hibernation she discovers over 100 years have passed ... yeah it's a bit of a setback. Now--a century behind her foes--she must find and finish them or Earth will become the next niiaH charnel pit.
Because you can be sure her enemies have been busy!
