The Unseen World by Patricia Correll is available in paperback and kindle.

I really enjoyed this book, so much I zoomed right through it in less than a week. It had me hooked from the beginning, and the further I got into the story, I found it harder to put down. Finally today, I sat down and finished it. I usually leave my reading until nighttime, but I decided I needed some me-time just so I could finish the story.
This book is a fantasy set during the feudal era in Japan. It follows the story of a young teenage girl who lives in a poor village. She’s set to become a potter and marry a young farmer, but quite unexpectedly her life changes. Sanami discovers she is a descendant of a mysterious, but extremely power clan that has the ability to tap into mystical abilities and cross over into the supernatural unseen world.
This young girl makes a deal that has her relocating to the Imperial city to study her new found abilities for a year, before returning home to her betrothed. During that year, Sanami adjusts to being someone of importance and has many adventures into the unseen world. She also makes some new friends, and one in particular has her emotions reeling as she comes to terms with all the changes in her life, and the possibility of new love.
If you like great description and marvelous character development, this book is for you. Patricia does such an amazing job weaving a story that makes you feel like you are right there in it. The story is also a wonderful depiction of Asian myth and lore that makes for a captivating and fun read.
