Dawn Caravan by Elizabeth Hunter

After this night, dawn can’t come fast enough.

For Ben Vecchio, everything has changed. His eyes. His diet. His new aversion to sunlight. But after a long sojourn in China, Ben realizes that the world he left behind hasn’t changed as much as he feared. He wants to leave his old life in the past, but there’s one job remaining that just won’t leave him alone.
Radu’s mystery is too interesting—and too profitable—to ignore. The problem? Taking on this commission puts Ben in the path of his old partner, the one woman he’s spent years avoiding.

Tenzin has been following Ben at a distance, hoping his ire might wane, but when he heads to Romania, her patience runs out. Ben is a new power in their world, and more than one vampire will be eager to test him.
Ben and Tenzin need to work together if they want to find the truth behind Radu, his mysterious clan, and the treasure at the heart of the Dawn Caravan. One last job, then it’s finished between them.

Right?
