I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
And that is how I really feel.
It had a good crime plot, was not badly written or anything.
It just didn't stand out.
I got it free within Kindle Unlimited and found myself unwilling to read the sequel. That says it all, basically.
The characters remained very pale and unclear. The "relationship" part was done in three sentences, could have done better with leaving this out, if not having the story go anywhere and it just remained largely uninteresting to me.
