Hmm, it wouldn't be 1st person singular (that would be you). You're not talking to anyone, so it's probably not 2nd person singular. Since it's an object (he, she or it) you're talking about, it's 3rd person, and only 1 book makes it singular.
Look at the conjugation of the verb Estar and with the "clues" I've given you you should have it.
