I cannot recommend this book enough. It is so rare to find a novel so connected to the migrant experience, and this hit all the right notes for me - that feeling when you don't want to be considered a failure or can't communicate what you're going through so you cut off contact, the weird romanticisation of your "home" while simultaneously talking it down with your new compatriots, moving between differently politicised landscapes and having aspects of your identity blown up or swept under the rug depending on where you were and who you were with... I could just relate to it all so much. I also loved how it explored two completely opposing experiences of migration from Nigeria to "the west", and how it also observed the differing experiences of other migrants through the eyes of our main characters, with them judging "other kinds of Nigerians" and the black Caribbean migrants. I just loved the depth of her characters and the honesty with which she discussed the politicised/tricky issue of race. 
 I still think about this book and the perspectives presented in it as a result, and it further gave me an entirely new perspective on my own experiences with migration/return. I feel like anyone would benefit from reading this book!
