It is heartrning that she still wants the books sent to her...in spite of her parents' rejection of Islam.
I would suggest perhaps one of two potions:
1. sednd the books to her to the address she gives, but in a plain package, that as she requests, does not reval what is inside. make sure the return address of the Abha Communities Center reveals only that name...the Communities Center... not mentioning anything about Islam or dawa.
2. Respond to her before sending the books, to see if there is an alternae address (perhaps of a friend or teacher or someone who will be discreet and not reveal this to her parents)...at which the books requested can be sent. Then, that person could contact her when the books arrive, without her parents' knowledge.
I pray that she does recieved the requested books, and that all works out well with her.
