I really loved this book. On the surface, it's a story of a couple, from the charming (or maybe creepy) way they meet, jumping ahead to years into their marriage. But it delves way more into what makes each of them who they are, from events in their childhoods (each traumatic in different ways) and before they meet (college/finding themselves). Are they a true match, or were they simply seeking in each other something they felt they needed when they met, both feeling alone in a big city? and is the person they each fell in love with the real person, deep down, or a facade of how they wished to present themselves and be seen? Are they still compatible many years later with a kid on the mix? The book has some really fascinating tangents about monogamy, love, relationships, etc, and these characters are realistic, flawed, believable, lovable. If you really love a complex and fast moving plot, this might not be for you, but if you like to dig deep into characters, psychology, and sociology, read it!!
