 Review - 
 Lord of the Abyss by Nalini Singh is the 4th and final book in the Royal House of Shadows series. It is the darkest and most compelling book in the series. It draws you into a world that whispers of a tortured hero and a heroine that breathes life back into his stale and bleak existence. She also harbors a tortured past and as daughter of the enemy she fears the hero finding out her true identity. She came to him with a mission. I mission that she hopes will stop the evil that is her father. She didn't count on falling in love... 
 Lord of the Abyss is well written, fast paced and very entertaining. You will find yourself rooting for the hero and heroine while hating the dark Blood Sorcerer. It's is ultimately a story of love and the battle between good and evil. It dwells even farther into this with a hero that many feared and saw as a monster, including himself. It's an enchanting and dark fairytale that will stick out in your mind as completely unique. If you're a fan of Paranormal Romance I urge you to find some time to sit back and enjoy this story as well as the others in the Royal House of Shadows series. 
 To best grasp the overall arc of the series it is best to read the entire series in order from the first to the last. This final installment is highly recommended.
