Lotus Blood

Nam's life stinks. She loathes having to live in baking hot Thailand where she hates the food and can't speak the lingo. Now her boyfriend back in England has dumped her and she has no idea that the Mara, the Buddhist devil, wants her for his blood collection - the descendants of the offspring he's sired with mortals down through the centuries.

That all changes when an earthquake, then tsunami rips her parents' hotel apart, drowning Nam and her mum and thrusting them into the Buddhist Limbo.
Together they fight off the demons sent by the Mara to seize them and Nam discovers that her blood-line might be a bummer, but it gives her the power to blast demons out of existence.
Her mother knows the Mara will pursue Nam through every plane of existence and offers herself as his slave in return for Nam's safety. Nam fails to stop her making the pact and is torn away and sent spinning back into her life in tsunami ravaged Thailand.

Nam's battered and guilt racked, alone in the knowledge that her mother's dead in this world, but living on as a slave in the Mara's kingdom of pain.

Now Nam must harness and hone her new found powers, find a path back to the Underworld and break her mother out of the devil's clutches. Going after the Mara's going to mean dying all over again and that sucks, big time. But if Nam fails, she not only loses her mum, but loses her own soul her as the devil's plaything for eternity.
