Alien adventure (Part 1)

Jason had been sitting at home when the white light came into his living room, sucking him into a flying ship hovering in the atmosphere. The aliens were quick to experiment on him, placing his brain into the body of a woman they had abducted a few years ago. They had grown quite fond of her before she got injured. The aliens looked to replace the vital body part, not realizing human anatomy or quite what the brain did. Jason was shocked when he awoke with a strange new body. But he also noticed a strange new gun in his hand. Maybe he could fight back from whoever did this to him...
