My Sister, the Serial Killer

I enjoyed this a lot! I don't normally read a lot of mystery/thrillers but I saw this on Netgalley and something about the title/cover just grabbed me. It was short and fast-paced but still had a fully-developed relationship between the two sisters, and a really dark sense of humor to it. The details about life in Lagos were interesting to me and set it apart from a lot of other mystery/thriller type books.
