"Blood Knot" by Tracy Cooper-Posey

Very unusual story about Winter, a professional thief, her partner, Sebastian, and his sire, Nathanial, a thousand year old vampire.  Winter is able to manipulate her biology and the biology of others by touch; that's how she changed Sebastian from vampire back to human . . . accidentally.  They split after that but reunite when Nathanial shows up with one last job neither can refuse.  Well written and surprisingly original story with unique characters that kept me reading.  271 pages (Kindle edition).
