OP here. Well, success didn't last long -_- it's a long story but, basically, I found out the publisher was majorly screwing me behind my back, so I had to protect myself and sever the contract. Of course, the book was immediately removed from all points of sale.
Good news is - my agent has just found me a publisher for an English version (minor publisher, but still), so I guess it was more of a case of 'a door closes, a gate opens'. Not even sure if that saying exists in English but whatever.
In the meantime I'll link one of the good reviews the original Italian got - doxing myself but I really don't see who would give a fuck.https://ilrifugiodellircocervo.wordpress.com/2015/09/25/mai-la-stessa-tre-volte-di-cristiano-montanari/
