I had really high hopes for this one as I love outlander/time slip novels and historical romance. I was also intrigued by the setting and premise but sadly it didn’t work for me and I DNFd at the 50% mark. Let’s start with what I liked enough to read that far:
-The book got better once Isla time travels, with the setting descriptions! I enjoyed the cultural descriptions and learning about Japan/Samurai culture
-Like the switching POVs between Isla and Keiichiro but occasionally switches mid chapter which caused some whiplash. I did prefer Keiichiro’s chapters to Isla’s.

Now what made me decide to DNF:
-Some of the writing is a bit meh with telling over showing
-I hated the pop culture references of MySpace and the type of cell phone Isla had. I don’t enjoy this in books and it gives me secondhand embarrassment but that’s a personal thing and maybe only bugs me
-The dialogue also felt stilted and cheesy at times 
-Could be confusing the way the names were written. In Japan the surname comes first and the author did that most of the time but sometimes she’d switch to the English way and it made no sense!! It ended up being confusing, just stick to one way or the other and be consistent.
-Another inconsistency was a scene with Isla and Nene. They had met a couple chapters before so then why did they later act as if they were meeting for the first time? This book could’ve used a heavy round of edits because it was all over the place in some areas. Being rushed in some places (like a battle scene) but then dragged out painfully in others so the pacing wasn’t great.

It fell flat in a lot of areas and wasn’t entertaining enough to continue, after the first half I still just didn’t care about the characters or story. Others may enjoy this more than me and I’d be willing to try to read the author again in the future.
