Spectator books of the year: Molly Guinness on the ‘oddly adorable’ New York dentist

What You Want, or the Pursuit of Happiness by Constantine Phipps (Quercus, £20). This is a deeply eccentric book — a novel entirely in verse set in a theme park that takes in the history of philosophy and the tale of a disintegrating marriage. In a few witty rhyming couplets, my cousin Constantine Phipps can sum up an entire character with all its foibles or a whole system of ethics.
