13 Days of Midnight

When Luke Manchett's estranged father dies suddenly, he leaves his son a dark inheritance: a Host of eight unique, powerful, and restless spirits. Unfortunately, Luke has no clue how to manage them, which the ghosts figure out pretty quickly. Armed with only his father's indecipherable notes, and a locked copy of "The Book of Eight", Luke struggles to adapt to his new role as a necromancer. --From dust jacket flap.
