Not a thriller. Actually very boring, slow and predictable. Reading this was yawn inducing. I don’t get the hype.

Crazy opening but good read overall . I really wish Korede would have stood up for herself and stopped feeling like she had to protect Ayoola.

Very enticing title, but don't go into this thinking it's a thriller. Much more of a drama that centers around family dynamics. It's about the relationship between 2 sisters. If you grew up with a younger sister, I think this will hit a bit more for you. Also, I highly reccomend the audiobook. The narrator's voice is beautiful and she brought life to the Nigerian accent that my internal thoughts never could.

My Sister, the Serial Killer is a sharp, engaging novel that explores the complicated bond between two sisters. Korede is practical and dependable, while Ayoola is charismatic and impulsive, creating a tense and compelling dynamic. Braithwaite balances dark humor with unsettling moments, keeping the story fast-paced and absorbing. The book also raises thoughtful questions about loyalty and the lengths we go to for family, even when those choices are morally unclear. I think the author could have done a bit more with this, but all in all I found this to be an enjoyable read.
