Your translation is fine.
"Is" always follows the part you're alsoing. It might be a bit difficult to get used to it because in English you don't usually specify such things.
Könyvet is adtam neki.
Neki is adtam könyvet.
Both can be translated as "I gave them a book / books too.", but in the first case I also gave them something else, while in the second one I gave books to at least one other person too.
