The Time Swindler — Eileen Sheehan

Cast out of his realm, Swindler, a dark fae, makes a deal with a human, Albert Fielding, to supply him with people who he can syphon their life energy from, thus stealing time from them. In exchange he promises Fielding and his ancestors unlimited wealth. As the years progress and the generations move forward, the deal becomes far more complicated and sinister as the ancestors seek the perfect life force supply for Swindler by way of their long lost cousin, Josie. Will Josie fall prey to their wickedness?
