Astronaut Down (Astronaut Down #4)

Douglas has crash-landed in a new reality. He's stranded there, his ability to send a transmission is gone and the worst thing possible has happened: In this reality, he's a hero and everything he's ever wanted exists... including his wife. But it all comes at the expense of his own reality. Every thank you, every gift and every dream come true is now torture since he can't save the dying world he once called home... or can he?
