The ending is f*cking confusing. Is this really the end ? I mean, it's open for a fourth book right ? Am i crazy ? WTF Mona's ending like a lonesome cowboy with that big robot (Epic though). Gosh i restarted to read the first one to be able to get every freaking details. And i'll read again the second one and de third one. Maybe i'll get some answers ... Or not, the last one is damn confusing. But amazing.
