I fairly enjoyed this to start with, it was all a bit murderous and funny.
A fairly average person working in a newspaper who clearly had a dark history and from pretty much the get go was killing people who "deserved" it.
I was enjoying it but the end just seemed to leave a lot to the imagination, maybe it will explain it in the second book of the series but I'll not give any spoilers.
The end also switched into a bit of a rom com which I lost interest with but it was just maybe the last quarter, so I would say it started strongly, middle was strong and the end I thought was poor.
As a standalone, but as a series it may, and probably will complete this story.
It was worth the read though and over all I did enjoy it, I've already ordered the next book in the series so that's the sign I enjoyed it enough.
