difficult sentence

[adel87]

dear in this
It was nearly midnight, and he was lying on his stomach in bed,
the blankets drawn right over his head like a tent, a flashlight in
one hand and a large leather-bound book (A History of Magic by
Bathilda Bagshot) propped open against the pillow. Harry moved
the tip of his eagle-feather quill down the page, frowning as he
looked for something that would help him write his essay

i've not understood
1)was lying
2)drawn right over his head what is the meaning of right over
3)leather-bound what is the meaning leather-bound
thank you

1) 'lying' is a present participle of 'lie'. 'Lie' means 'be in a horizontal position'
2) 'right' means 'just' here. It isn't very important in this sentence. It means that the blankets covered his head.
3) here you have 'leather bound books': leather bound book - Google Search

Yes, mmnasny is correct. And it is also true that "right over" is an interesting phrase. In this situation it doesn't mean very much. It just emphasizes that it is fully over his head. Often we will say something like: "Throw the tarp (tarpauline) right over the leaky roof" to emphasize that you want it to go over the whole thing -- and, perhaps, as quickly as possible.
We might also say "I'll be right over," which means, "I'll be there right away," which means "immediately." It is, indeed, an interesting word.
