I pre-ordered this novel for my wife. Sadly it never arrived. It was apparently sent with Royal Mail, should have arrived on the 21st of November. Spoke to Amazon and they believe it is lost, so got a refund.
I encountered this novel in a local Waterstones and bought it immediately for my wife. So even though Amazon did not deliver and it got lost on the way, I still wanted to leave feedback as my wife read through the novel as soon as she got her hands on it and she loved it.
The novel had a few spelling mistakes, calling a guy she instead of he and so forth. I suppose the spelling mistakes are the only 'bad things'. Some translations were a little weird, she said that reading Master Kakashi and Master Guy didn't quite do it for her so every time it came up, she kept thinking Kakashi Sensei and Guy Sensei. Apparently Naruto's Shadow Clones are translated to doppelgangers.
The novel itself was great she said, the story was intriguing and she can't wait to read the next one. I'm not that much of a fan myself of reading, but my wife had a very in depth conversation about it, so I know what it was like. It would actually be quite fun if they made movies out of them.
This novel is recommended to any Naruto fan!
