>Today, I want some feedback.

Reading between the lines, was this a book that you wrote? If so, badgering people you know into reading it is incredibly poor form and is not going to get you any useful feedback—it's just going to alienate your friends and family. If you want feedback, there are subs like r/BetaReaders for that purpose.

If this wasn't something you wrote....then it's still rude to expect your coworker to read it. At that point it's no longer a gift to her, but an obligation that you imposed on her for your benefit. If she reads it and wants to talk about it, she'll let you know. Otherwise, don't badger her about it.
