Second paragraph of third chapter:
“Nobody.” Jes repeats his answer for who knows how many times. He can’t blame the big guy for being cautious. He hadn’t planned on telling them about his ability or the Institute so soon, if at all, but the equipment failure happened, and people were going to get hurt and he had to show them some reason, some value he could add to their operation. Disclosing his ability just opened the door.
Space opera where our protagonist has psychic powers over the forces of gravity. Some nice ideas and good treatment of gender, but not startling. You can get it here.
