Sean McLachlan has come out with his latest novel. Called The Quintessence of Absence, it's out now on Amazon, Amazon UK, and Smashwords. The blurb goes:
Can a drug-addicted sorcerer sober up long enough to save a kidnapped girl and his own Duchy?
an alternate 18th century Germany where magic is real and paganism
never died, Lothar is in the bonds of nepenthe, a powerful drug that
gives him ecstatic visions. It has also taken his job, his friends, and
his self-respect. Now his old employer has rehired Lothar to find the
man's daughter, who is in the grip of her own addiction to nepenthe.
Lothar digs deeper into the girl's disappearance, he uncovers a plot
that threatens the entire Duchy of Anhalt, and finds the only way to
stop it is to face his own weakness.
