According to the rules here, if the sentence contains an indirect object it should have an indirect object pronoun. Therefore, your original sentence should have been:

Léenos los libros a nosotros.

I have read other articles stating that if the i.o. follows the verb, this seemingly redundant, i.o.p. is not used.

Ignoring that, to replace the nouns with pronouns:

Affirmative sentence:

Léenoslos. (being an affirmative, informal command the pronouns must be appended to the verb. The 3rd, person, singular, present tense, indicative mood verb ending is used.)

Negative sentence:

No nos los leas. (being a negative, informal command the pronouns must precede the verb and the 2nd person, singular, present tense, subjunctive mood verb ending is used).

these are the words to choose from to people answer the question:

nieta--yerno--tia--tio--primo--nuera--abuelo--cunada
