Booked for Murder - Vigilante Magical Librarians, #1

Life as a bodyguard and driver for the rich, famous, and powerful is dangerous on a good day, and after sustaining a crippling injury while on duty, Janette's left with few options. Having signed a 'for life' contract but unable to work, she uses her skills to disappear. Her new life as a librarian suits her. Nobody cares she limps and sometimes requires a cane to walk. She's wanted for her knowledge, not her lethal magic.
She's surrounded by books, a woman's best friend. But when her former employer's best friend is murdered on the steps of her library, old loyalties and secrets might destroy her-or set her free. Teaming up with her co-workers to find the killer might keep her from being booked for murder, but unless she's careful, she'll find out exactly how far her ex-boss will go to reclaim what is rightfully his. Her.
For life.
