After Dark by Gena Showalter — book slip

In 'The Darkest Angel', winged warrior Lysander has lived for centuries without knowing desire—until he meets Bianka, a beautiful but deadly Harpy from the bloodline of his enemy.

Determined to lead the untouched Lysander into temptation, Bianka finds herself in a dangerous dance with the iron-willed demon assassin.

Meanwhile, in 'Shadow Hunter', vampire hunter Damon Brock's first assignment with the Execution Underground takes him to Rochester, New York, a city teeming with the undead.

There, he encounters Tiffany Solow, a fierce and ruthless hunter who works solo. As they join forces to eliminate the local covens, their beliefs are challenged by their growing attraction.

First in the 'Lords of the Underworld' series.
