Book excerpt: Babe Walker, center of the universe, is a painstakingly manicured white girl with an expensive smoothie habit, a proclivity for Louboutins, a mysterious mother she's never met, and approximately 50 bajillion Twitter followers. But her "problems" have landed her in shopping rehab-that's what happens when you spend $246,893.50 in one afternoon at Barneys. Now she's decided to write her memoir, revealing the gut-wrenching hurdles she's had to overcome in order to be perfect in every way, every day. Hurdles such as: I hate my horse. Every job I've ever had is the worst job I've ever had. He's not a doctor, a lawyer, or a prince. I'll eat anything, as long as it's gluten-free, dairy-free, low-carb, low-fat, low-calorie, sugar-free, and organic. In an Adderall-induced flash of inspiration, Babe Walker has managed to create one of the most enjoyable, unforgettable memoirs in years.
