I have to admit, though, that the fact that Leine was a former assassin bothered me a lot in the beginning, even though the author stresses the fact that she killed criminals. I kept wondering if I was going to forgive her for that. Surprisingly, I did. Leine comes out as a very human character who is deeply sorry about her past and who wants to reconcile with her beloved daughter. This emotional subplot about her and her daughter really brought the story to a higher level for me.
Another thing I need to point out, just for those sensitive readers out there, is that there's a lot of foul language.
In short, I highly recommend Serial Date to those who enjoy murder mysteries with a touch of satire.
