Braithwaite has written a dazzlingly dark novel that pitches the blood of murders against the blood that binds two sisters, sometimes reluctantly together. With perfect pitch, she unrolls a story set in modern-day Lagos as nurse Korede is alarmed to find her serial-killer sister dating the handsome doctor with whom Korede herself has long been in love...

One of the things I like about this is that Braithwaite doesn't hang around: when so many novels are padded full of waffle, this one gets to the heart of the matter from page 1. Not that that means this lacks depth: on the contrary, we're kept enthralled by both the 'present' story of what's going to happen in this oh-so unconventional love triangle, even while we're also intrigued by Ayoola's psyche and her complicated, layered relationship with her sister.

Buoyant and generous, with a welcome dose of humour and some sharp points about gender and power, this is refreshing and intelligent, with a hint of Ottessa Moshfegh's trademark off-kilter storytelling - definitely a writer to watch.
