Entasy by Brynn Myers
Kylah is the granddaughter of two Celtic goddesses but due to a tragedy Kylah's memories were taken to protect her. She has no idea who she really is but soon she will find out...soon she will have to confront her past in order to save her future.
This sounds like the Greek/Roman gods trend has hit celtic mythology! I think it sounds very exciting, and I can't wait to get my hands on it.
