Them would be the correct pronoun for this sentence because books is plural and is an object, so its pronoun must be third person. The 3rd person plural pronoun in English is they, and its objective/accusative form (the form used when the item is the object of a verb) is them, so there's your answer.
It's in 1 st person point of view
Laura judges Rita by looks instead of actually finding out by asking. Never judge a book by its cover as they say. Also Laura focused more on Rita than herself causing herself to fall behind. Hope it helped.
