It tells the story of two Nigerians, girl- and boyfriend at school, callled Ifemelu and Obinze, who both travel to the west as adults to find the "better life" they have dreamed and talked about as students. Ifemelu gets a scholarship to the US, and Obinze finds work as an illegal immigrant in the UK. The book is partly their love story, but more about their experiences as immigrants, their relationships, how it is to be black (which wasn't an issue back home) and eventually how they return to Nigeria and pick up new lives there.
Ifemelu takes to blogging about her experiences as a "Non-American Black" and the sections on her blogging are brilliant, including some of her posts and readers' reactions.
For me the parts I read most avidly were the transitions, both how Ifemelu arrived in the US, and then how she felt about returning home after fifteen years abroad. I was surprised how completely I related to the descriptions of her initial reactions to the west. Her shock that it was not all as clean, wealthy, and beautiful as she had come to believe. Her feelings of confusion about everything. Her disappointment with the fruit and vegetables.
This is such a rich book, revealing about what it is to be an ex-pat, and a returnee, a woman, a friend, a desperate job-seeker, a lover, a writer. I highly recommend it.
