For details. The boy is considered a wild child by the town, as he is always dirty, doesn't wear underwear, and wonders all over town late at night alone. In truth it's because his grandparents don't let him have the basics, while they have a TV in their room. Very important is they don't let him in the attic (where the child's mothers, old clothes and stuff are kept.) In truth he went up a previous summer, dressed up, went out into town as a girl and fell very ill.

While at the neighbors he dresses up, spends time with the girl who originally hates/is jealous of him. They start to get along as sisters. The girl's farther takes the "boy" bowling with the others males in his group ("the four families" who are rich, hold lots of influence in the town) Their is trouble.

Turns out that the boy is a victim of serious abuse, including having a medical file full of insults.

In the end it turns out the "boy" is actually a girl, with ovaries, but no uterus. A condition the girls mother also has. And the neighbors were friends of the "boys" parents. The grandparents were just going to dump the "boy" on the neighbors, but died on the way to their holiday.

Then I think it was called Emma or Emily. And the author took it down before leaving bigcloset. Not seen it uploaded elsewhere.
