I loved this book! The cover first pulled me in and then the summary on here sealed the deal for me. I loved that this was a YA Psychological Thriller with lots of Japanese roots. 
 Since I'm a fan of Japanese I was nice to read a book where Japanese had a lot of influence and was mentioned a lot in the book. Reading about their culture and the myths and legends they have was interesting and educational, I found myself not being able to put the book down, except when I had to. 
 The Girl from the Well had ghosts and stuff from Japanese legends, so there were a few Japanese jargon (words) throughout the story that I felt proud in knowing, even without needing the explanation, because I watch lots of anime and read manga so I sort of picked up a few of the words. Still, me being obsessed with Japanese stuff, I would have to say this was a well written story that incorporated the Japanese culture, modern times, and supernatural elements well to make an excellent story. Right off the bat there is action happening all throughout the book and it never stops. 
 Whether it was things happening to Tark or something that Okiku was doing, I was never bored with the book. Although I admit I was a little skeptical because Okiku was telling the story and not Tark, I quickly came to realize that it was good choice after lots of things were happening and the only way it could properly be explained was by Okiku. Also, there wasn't that much dialogue in here and I admit that I usually get bored with lots of details and I skip to the parts with the dialogue, and I find myself lost later on the book, this was not the case with The Girl from the Well. I was totally hooked and absorbed the details in seeing as how they were rich in information about Japan or what was going on with the story. 
 I honestly can't wait for the 2nd book to see what happens next. Although, it might not be a direct sequel, come to think of it, it could be about another set of characters but Tark and Okiku still being mentioned, and I would have nothing against it seeing as how it would be interesting either way.
