Some small spoilers*
This was honestly a fantastic book if you love enemies who were friends at one point and might love each other. I love that Amari is such a badass in the end and Vincent learns to support her doing what she wants. Fully recommend if you want an unhinged FMC.
The timeline for me was a little... off? The first chapter has a timeline/scene change without notice, theres a 2yr gap that seemed a little unnecessary and then Amari somehow becomes a serial killer in only a year while being tortured.
My only other thing to say is if you don't like cheating between the main couple? Don't read this. They both do it.
