The Reckoning - Jim Newport - Bog

Ramonne Delacroix - the enigma. 175 year old French vampire. Resident of the kingdom of Siam and modern-day Bangkok. Murderer with countless victims. Witness to history in three centuries... Hitman.
He has acquired the journals of the historic journey that he made in 1858 with Henri Mohout to Southeast Asia. Seeking the source of his powers he plans a journey back to the ancient temples of Cambodia and a fateful encounter with Zhoupeng - the mighty devil who "turned him" so many years before. Ramonne vows to put an end to his reign of evil over the poor land.
Martin Larue, rich expat whose life was changed forever by his encounters with the vampire, has taken his soul-searching a step further, and with his girlfriend Areeyah, has founded an orphanage and school in Cambodia. He rescued 12 orphans from a life of scraping through a giant rubbish heap outside Phnom Penh and took them to the hamlet of Siam Reap, outside the gates of the ancient temples of Angkor Wat. His 'brood' as Martin calls them, have become everything to him.
However, Martin learns there is a serial killer in the area - preying on the native's superstitions and beheading its victims. Martin is horrified by the news as the killer's recent activities are cantered right where his school/orphanage is located.
Ramonne arrives in Cambodia. Martin is relieved he's there - he needs a saviour.
The battle between two powerful demons is a battle with dire consequences for the world. Zhoupeng, now not only drinks the blood of his victims but he has learned through studies of the ancient Khmer sorcerers texts, to consume their souls - allowing him to grow incredibly strong. His evil reign will soon know no bounds. If he is to defeat him, Ramonne must eventually rely on the sacrifice of 'one with ultimate innocence' -
One of Martin's children must die...
