Ok, I officially like both the sequels to The Painting of Porcupine City better than the original book.
Glad I didn't wait to read this one. It's basically an extended epilogue to The Painting of Porcupine City, which you probably know from the title if you read that one. This time it's focused on Mateo's Brazilian friends and family, mostly centered on his cousin Vini. 5 years on, Vini is not coping well. His friends and family don't know how to help.
FYI, there is no romance here, this is about endings, not beginnings, and Vini is straight. But this is a much better wrap up to Mateo's story than we got before.
I didn't really take the time to analyze it, but Monopoli's doing something a bit odd with POV here. Sometimes it's Vini first person, sometimes Vini third person, and then Mateo's mother and Tiago a couple times. It didn't feel like old fashioned omniscient. I was slightly jarred a couple times by the switches between Vini first and Vini third as I didn't really see an obvious purpose for it. It only changes between scenes though, to the best of my recollection, so it didn't feel sloppy.
While I do think you can read Ollie's book completely independently of PoPC, this one makes more sense to read after.
