Grave Reckoning. The Resurrectionist Papers, #1

Left for dead in a mass grave he awoke immortal. Commanding rare magics. With no memory of who he is. Solving crimes brings him closer to the truth. Bounty Hunter, Greysen "Blade" Mallory can find anything-except his lost memories and missing past. Left for dead in a London mass grave in 1726, he awoke immortal with a command of rare magics but no manual. When he's hired to pursue a bounty on the Oregon Coast, Greysen awakes to find a dead man and local police scouring his bungalow for clues.
Including beautiful, eagle-eyed Detective Harlowe Keller who labels him a person of interest. Professionally and personally. Forced to work together, Greysen and Keller search for a killer raising the dead all along the coast as a magical war rages between the self-absorbed goddess Hecate and the quirky god of Death. The killer has clues to the fabled resurrectionist papers, documents that may hold information about Greysen's past.
As blood magic begins to appear in dangerous and public places, Greysen Mallory and Detective Keller wage their own war to stop the destruction. Grave Reckoning is the first book in The Resurrectionist Papers, a romantic paranormal mystery/suspense series featuring immortal bounty hunter, Greysen Mallory and former army sniper, Detective Harlowe Keller who solve crimes despite a host of immortals warring for territory on the Oregon Coast.
