Cosmina is set in the world of Cantamen, where everybody has an affinity to magic and some an affinity to dark magic. This book is a medium-fast pace fantasy with a lot of action. It is heavily plot driven. You follow codenames: Cosmina, Nix, and others across many places in Cantamen and eventually to Earth in their quest to be a more proactive group against Council Witches who hold those with an affinity to dark magic prisoners (amongst other things).

Personally, I struggled to get through this book - mostly because it didn't focus on characters long enough for me to hold interest. I prefer a character-driven story, especially when it comes to a fantasy book. I loved Nix and Cosmina though. I wish I could've read more of them.

I'd recommend this to people who love a plot-driven fantasy, fade to black romance, major action-adventure with magic involved.

Disclosure: I received Cosmina as an ARC in exchange for a fair and honest review.
