Heart of Obsidian (Psy-Changeling, #12) - Nalini Singh This book was A-MAZ-ING. I can't believe how amazing this books is. It broke my heart several times but it also mended it every time. I honestly can't start to write a review about this story, I feel like there aren't enough words to explain all I felt while reading Heart of Obsidian. I am so in love with everything in this book. You belong to me. I'll never walk away from you. I'm glad you're mine. I won't ever let you go.
