I had a good time reading Realm of the Blue Mist, but not without some reservations.  The plot is great (I do love portal fantasy), I love the mix of fantasy and science fiction, and I like the characters. It is however let down by at times shaky worldbuilding - I got the sense that the author understands this world, but as a reader I had a lot of unanswered questions and things that confused me. I realise that it's book one of a series and answers might come later, but it did harm my enjoyment a little bit. 

I really love the art style. I read that it was inspired by manga and I can definitely see that influence. The world of Rema is beautifully depicted.  I couldn't help flicking through the pages again after I finished reading.

Overall I probably will continue with the series, it has me intrigued to want to know what happens next.
