Kingdom of Lies (Imp Series Book 7) (1808)

Book 7 - Kingdom of Lies
Samantha Martin may be the leader of Hel, but she is also an imp in debt to a sorcerer. Luckily he’s vowed to wipe away all the favors she owes for one job – retrieve a stolen gem.
But Gregory also needs her help. Interdimensional rifts are opening, spilling supernatural creatures into the world of the humans. Locating and closing the gateways takes a team of two – an angel and a demon.
It’s the opportunity Sam has been waiting for, the very thing that might allow demons and angels to put aside nearly three million years of hate. But the gem has a dark power – one that could shatter any hope of peace between heaven and hell. Which task takes priority? Sam is at a crossroads, where either choice leads to a dark future
