"awake to" is fine, if you're talking about a realization that has come to you over time: "After living with him for 18 months, I finally awoke to his selfishness". You may have been brooding about this text for a long time - in which case your usage is good.
But in the case of noticing something in a text, I think I'd use "was aware of" or "notice" or "was conscious of".
