The Order. Unbound (en Inglés) - Nicole Autumn

Amy is a 30-year-old, small-town librarian who lives a quiet life. When she finds a mysterious book in her library, she turns to her best friend, Charles LaRue, for help.

Things take a turn for the worst, and Amy finds herself restrained in a cabin in the middle of the North Carolina forest. Charles and his friends, Jensen Norwood and Leo Hutson are hiding a massive secret that will change Amy's life forever. But wanting her, isn't it.

The guys will help her learn the ways of The Order, a secret society that protects our world from the monsters that threaten to kill off humankind. She will face old demons who will do anything to destroy her and new ones who will plot her downfall.

Will she be able to accept who she truly is to protect herself and the ones she loves? Or will she crumble under the pressure?
