What kind of stories are there where boys gero berest?

I'm not sure what 'gero' refers to in this context. If you mean stories where boys have special powers or go on quests, there are fantasy series like 'Percy Jackson and the Olympians' that fit the bill.

I think it might be based on real events, but with some fictional elements added for dramatic effect.

I can't recall ever coming across a novel with such a bizarre premise. It could potentially be a very niche and unconventional work within a certain subgenre, but it's definitely not something widely known or common.

We don't have enough information to determine the exact kind of stories.

Well, there could be a story where the 1 teen and 2 boys are in a band. The teen plays the guitar, one boy is on drums and the other on bass. They struggle to get gigs at first but through their determination and the teen's songwriting skills, they start to gain a following and make a name for themselves in the local music scene. This story would involve themes of friendship, creativity, and perseverance.

I'm not familiar with the 'boys in thongs stories' so it's hard to say exactly. But perhaps there could be characters who are bold and not afraid to be different in their fashion choices.

They often love adventure stories. Stories about pirates searching for treasure or knights on a quest are very appealing to them.

Science fiction tales featuring brave young heroes facing unknown dangers in space or alternate universes could appeal. These offer opportunities for boys to imagine daring exploits and problem-solving.

Adventure stories can be great. They offer excitement and challenges that boys who dare to would enjoy.

It could be a coming-of-age novel, where the boys face various challenges and grow through their experiences.
