Bound in Black (The Vessel Trilogy #3)

Genevieve Drake is on a dangerous mission—to find the soul collector, Lethe, and enter the deepest, darkest level of the underworld, where no one has ever gone into and returned. But nothing can prevent her from going after the precious treasure Lethe stole from her.

Genevieve endures challenge after challenge against demon spawn and foul creatures while there, and each triumph strengthens her Vessel power, leading toward full awakening, at which time she will become invincible against the hosts of darkness. But when an old enemy makes a surprising appearance, she is tested to the point of breaking and risks remaining in this dark abyss forever.

When Prince Bamal finally reveals their secret weapon, will Genevieve have the strength to survive? Even more, when her guardian angel, Thomas, reveals his sinister secret, will she finally fall into darkness and forsake the fate of the world for her broken heart.
