Thieves and Thorns by Scarlet King

Rory wants revenge. The only thing standing in her way is them.
After she stealing her family spell book back from the museum exhibit it had been cruelly placed in after her grandmother’s death, a PI team is sent to find her. They make her a deal: she has two weeks to convince them not to turn her in, but they won’t leave her side until time’s up, or they hand her and the book over to the guards.

Vengeance, secrets, lies and heat that threatens to break her resolve to hate them all…

This is a fantasy reverse harem book, meaning that the main character does not have to choose between the love interests. MMFM.
