I'm just imagining someone new to her work stressing over this decision, and it's making me laugh. Honey, just pick one. You're about to have a great time. It's like choosing which flavor of excellent gelato to eat first. You can't lose. The fact that we have 50 different opinions on order just proves how many good options there are. The discourse is part of the fun, but the actual reading is the reward.
So take a deep breath, close your eyes, and point. Or, you know, read the first line of each on Amazon's 'Look Inside' feature and go with the one that grabs you. Trust your gut. It's a book, not a marriage proposal.
