Allison O'Malley's plan is to go to grad school so she can get a good job and take care of her schizophrenic mother. She has carefully closed herself off from everything else, including a relationship with Ethan, who she's been in love with for as long as she can remember. 
 What is definitely not part of the plan is the return of her long-lost father, who claims he can bring Allison's mother back from the dark place her mind has gone. Allison doesn't trust her father, so why would she believe his stories about a long forgotten Irish people, the Tuatha de Danaan? But truths have a way of revealing themselves. Secrets will eventually surface. And Allison must learn to set aside her plan and work with her father if there is even a small chance it could restore her mother's sanity. 
 I really wanted to enjoy The Forgotten Ones more than I did. The cover and the synopsis really drew my attention. This was also my first New Adult book that wasn't strictly contemporary. In my honest opinion, I felt that it was too short. There were quite a few plot lines that were going on. As soon as the plot would go in one direction and take off, the book would diverge onto more mundane topics. 
 I never got a true sense of the mythology. However, this could come in later on in the series. The pace in The Forgotten Ones is a quick one. But with the quickness comes a lack of concrete world building. Unfortunately for me, I really need that structure in the first of a series to keep my attention for any sequels. While this wasn't for me, there is plenty of action to appeal to paranormal readers. It may just be your next favorite read.
