If you want the book, you will have to pay them one Tweet and several powers, most of which are not necessary:
1. Read Tweets from your timeline.
2. See who you follow, and follow new people.
3. Update your profile.
4. Post Tweets for you.
5. See your email address.
You're asking for more information than you actually need, which is looked down upon. Why do you need to post tweets for me, update my profile, see who I follow and follow new people for me? This does not abide by the rule of least-privilege.
