This is one of those book that are marketed as YA but they could also be marketed as dark fantasy/grimdark as there's violence, gore, and the characters flawed and morally grey.
That said I enjoyed and think that the author developed a fascinating world and intriguing characters.
The world of The Keeper of the Night is complex, dark, and I loved how the author made it so fascinating.
The characters are well developed, not always likeable, intriguing in they're being damaged and flawed.
It could have be a 5* but the brusque start ten years after the first book made being involved a bit harder. A summary of what happened would have helped.
I enjoyed it and enjoyed the series. Can't wait to read the next book by this author.
Recommended.
