Although Koomson generally writes thrillers, this has the pacing and character development of literary or contemporary fiction and the slow building unease of a suspense novel.

The character development is done in an interesting way. You meet these women as fully form, but in perfect adults and receive occasional flashbacks to the past. This allows us to see a full circle journey for each woman and gain a better understanding of their current motivations for actions that would otherwise seem Illogical 

I think this is an interesting take on the revenge trope. These two women with a similar past creeping towards  a collision course kept me interested. It’s a large book, but I was never bored.

Some of the suspense did resolve itself along before the end and I think that that will be a decision. The author made that will frustrate some. For me, I enjoyed the story enough to stick with it. That does mean that the last quarter of the book doesn’t hold much in the way of tension.

Ultimately, I like the character development and worldbuilding and interpersonal relationships described in the novel and would recommend it
