Echogenesis

I stopped reading when (1) a character believed they were on an alien world because there was no moon in the sky, and other characters didn't point out the flaw in her reasoning, (2) two of the characters suddenly decided to have sex in the nearby forest in the middle of the night and it was blamed on the fact that they were suddenly the equivalent of eighteen years old and their hormones had become super active, and (3) the name of a character suddenly changed to that of another character in the middle of a scene. There were other less problematic things in the writing as well, but the three issues mentioned above were enough to make me stop reading.
