First of all: I doubt Drvenkar is for everybody. His writing (narrative) style is probably something you either love or hate. I for once love it. Either way, what we can agree on: It's something very different.
So here are the things you might want to know about Sorry (don't say I didn't warn you). It has multiple narrators. And different point of views. There's all of it: First person POV, second person POV (Drvenkar does that brilliantly, his other most brilliant Thriller Du is written completely in 2nd POV, and it's too awesome for words) and, of course, third person. You can never be sure if all narrators are always reliable, not because they lead you on willingly - they just don't know any better. And you, the reader, know little to nothing. It takes a while until you even figure out who all of these narrators are. Some stay anonymous for quite a while. But don't worry: It will all add up at some point, and the moment of clarity will feel so very rewarding.
See what happened here? That is Drvenkar and what he does to me. Narration and plot are much alike: you just never know who's behind it, you never know what's coming next. Everything could happen - or maybe nothing at all?
Sorry is about four friends, all sad existences on their own. Together, they rise to fame and fortune when they found an agency that apologises for others. As you might guess by now, guilt, responsibility and shame are central issues in this book. Morals and ethics are, in a way, too. The plot is fast. It's brutal. It made me sick in a way - humans can be so evil. I really had to put the book away for a few moments to catch my breath. And then, when I read on: another twist. And another turn. And another one. And I wonder: How did he... no wait... really? And I read on because I just can't stop.
And if you're now still not sure whether this is your thing or not - well, I won't tell you anymore, because you'll just have to try for yourself. If this kind of dark story and different narration is your thing, you'll lose yourself in this book. And you'll love it. 5 stars, what a question. More, Mr. Drvenkar, please, give me more.
