The Book of Secrets in Bloomington, MN

A bookstore with a million secrets...
Helena Davies just wants a job that will get her out of her parents' basement. Instead, by the end of her first day at Abernathy's Bookstore, she has a dead boss in the basement and the news that she is now a part of an endless magical war.
Abernathy's is the world's only living oracle, and Helena is now its custodian. Without any training, she must navigate her new world and find a place for herself within it. But there's still a murderer on the loose-and Helena might be next on his list.
