I'm giving this three stars as a generous indication of my enjoyment, but with the provision that I recognized pretty quickly that I'm not the target demographic. I didn't know anything about the author, going in, but I'd heard it mentioned on a podcast I like, "Pod Save the World" (which is also directed at a younger audience, but with politics it doesn't matter much), and I think that in my twenties I'd have have liked it better.
The "insider scoop" about working in the Obama White House, foreign travel, diplomatic gaffes, dance parties, etc. was fun, but the seemingly endless stories about feminine hygiene related disasters, IBS sagas, and angsting over whether to have children were not. Long stretches of meandering dullness. Fortunately, as well as amusing political stories, Mastromonaco tells endearing stories about her cats, and the books concludes with a really sweet picture of her with her Persian, Bunny. I'm a sucker for cats, thus the third star.
