Thanatos i.e. meaning Death in Greek language 
 He used to be a nice, cool guy. He was the father of all vampires. He loved his brothers and sister, his lovely home and his isolation. 
 He had to save the world of course, not to let his seal be broken and stop his half-lunatic brother from killing every living thing on the face of Earth from plagues. 
 But he was also one of the four Horsemen, proud and strong, dark and dangerous, high and mighty. 
 "Lethal Rider" starts with him drugged and powerless for almost 9 months by his brother and sister who were scared that he will snap at any moment. His precious virginity was stolen by a devious Aegis agent in the end of "Immortal Rider". Thanatos stays immobilized. He is seeing red, he is burning inside and he is planning death for the tortuous, manipulative, rapist Regan. 
 Okay, he is really really angry and scary. 
 The good thing is that obviously his seal is not broken yet, although everyone thought that it was connected with his virginity. 
 Regan. Poor, scared to death (literally), victim of the circumstances, very much pregnant girl. There will be no hole to hide when Thanatos (the future father) gets his powers back! 
 The book is their lovestory and it is full of revenge, a very slow process of forgiveness and large quantities of passion and love. 
 My favorite book from the Lords of Deliverance series!
