For weeks, the immortal warrior Aeron has sensed an invisible female presence. An angel-demon-assassin has been sent to kill him. Or has she? Olivia claims she fell from the heavens, giving up immortality because she couldn't bear to harm him. But trusting - and falling for - Olivia will endanger them all. So how has this mortal with the huge blue eyes already unleashed Aeron's darkest passion?
With an enemy hot on his trail and his faithful demon companion determined to remove Olivia from his life, Aeron is trapped between duty and consuming desire. Worse still, a new executioner has been sent to do the job Olivia wouldn't...
The Darkest Passion is the fifth book within the Lords of the Underworld series and to sum it up with one word - compelling. This is far my favorite book within the series.
Aeron is possess by the demon of Wrath. Violence is his middle name and has been marked for assassination by the angels.
Olivia was sent by the leader of the angels to kill Aeron, but as she watches him she falls head over heels for him. Risking everything, she falls from Heaven just to be near him. At first, Aeron wants nothing to do with the bloodied woman who he found wondering the mountain calling his name. But Olivia never gives up. She peruses him and seduces him. I love when heroines are strong willed, determined, and know what they want. She wanted him and, damn it, she would have him. However, Olivia didn't expect to have competition for Aeron's heart or that her former boss, the leader of the angel army, would strike.
The main couple were great together. Aeron fought his feelings valiantly, but he was vanquished. What kept me from giving this book a perfect score was the length. I've noticed a trend with Showalter's books, they can be very log and drag at some points. Another issue I had was with some of the side stories going. I would have rather had more focus on the main characters. But Aeron saved this book :)
