What is the book percy jackson the lightning thief about?

i have read the novel roll of thunder hear my cry by mildred d. taylor.

1. this isn't like any other story i've read or watched because it is about a black family in mississippi right after slavery in the u.s. had become illegal. most of the novels i have read were about slavery. another point is that the author of the novel used symbolism in a way i haven't seen before. for example she uses thunder as something negative meaning something bad will happen. but by the end of the novel, she made thunder a good thing.

2.   one character that changed during the novel was stacey. stacey is the eldest child of the black logan family. around the begging of the novel stacey was avoiding the white boy jeremy simms. he had a dislike for jeremy's family. but at the end of the novel stacey began to like jeremy.

3. the author starts the novel with the problem that the children of the logan family have to avoid the white kid school bus while walking to school.

explanation

old disney was more kid oriented as appose to new disney it's more teen oriented.i guess what i'm trying to say is new disney is way more mature and out there then old disney. for instance all you see in new disney is bf/gf drama and old disney it was nothing like that. kids are growing up and as coorpations like disney, nickolden etc they tend to follow what kids follow so they can have more views . therefore   they have inferred   that now days kids want to have relationships and stuff so that's what disney gives them.
