"Crimson & Steam" by Liz Maverick

I picked up this paranormal romance while browsing the shelves; it turned out to be part of the "Crimson City" series by Maverick and other authors.  This one centers on Marius, the leader of one of the main vampire families in a futuristic Los Angeles, and Jill, a reporter who is his human soul mate.  He can read her thoughts and emotions yet will not give in to his love for her due to his marriage alliance with a werewolf princess.  There's also a touch of steam punk with the inclusion of mechanical men (mechs), former humans partially turned into machines by the United States government.  This futuristic tale shares space with the backstory of how the vampires, werewolves, and mechs came to be created in mid-nineteenth century London.  I found the two plots to be very interesting and creative but the ending felt rushed, cheating us readers out of a satisfying conclusion.  320 pages.
