There has been so much hype surrounding the 12th book in Nalini Singh's Psy-Changeling series. With the identity of the hero and heroine kept under wraps until the book was released, readers have been on edge with anticipation as speculations reached a whirlwind of activity.

Singh had a major challenge on her hands. The big reveal could either blow readers away with her ingenious plan or it could become a major disappointment. However, had there ever been a doubt as to Singh's talent? A master of lyrical words and quiet, but intense emotions, Singh pens an epic masterpiece with the latest installment to the series. Readers will be floored not only by the reveal of the characters, but also by its lyrical detail and its heart- stopping emotions. HEART OF OBSIDIAN stands as one of the best books Singh has penned in her career.

Attention to detail is what Singh prevails in. Each page, each word is necessary in building a vivid, dramatic picture. The main characters are hauntingly real and claw into your heart with their broken pasts. Action on a level you've never seen before in this series takes this book from good to stellar. I felt that Singh poured her whole soul into the pages of this book. You can feel her heartbeats pulsing on the page.

In a dramatic and satisfying serving, HEART OF OBSIDIAN not only surpassed my high expectations, but Singh has ruined me for all other books. Passion on this level cannot be easily redone or replicated. Only Singh holds that power to blend lethal power and restrained passion and make it work.
