My goodness. Once I started this book there is no turning back for me. Forget fear of sequels!! If anything, this book took it to a whole new level!The plot of the book is the best part. Reading every plot twist and turn, I felt giddy and unbelievably happy. It dives in where the last book left off and I was back into Katy shoes bickering with Daemon. Yes, things have changed. Each chapter, Katy is getting closer to the Blacks and is changing. I like that the plot keeps moving so that the reader follows the trail like bread crumbs. You eat every piece fast only wanting another piece, and another, and another. Then you get to the end only to realize there's no more...The love interest in the book is plenty good. I LOVE Daemon sarcastic attitude and his ego. You can tell that this couples bickering will lead to lots of hardcore kissing and LOVE! I like that yes, they do argue and fight like a real couple but their feelings for each other are slowly coming to light. They don't say I love you right away and still, you know they love each other. I can't wait to read the next book!Onyx is an great addition to a series that I never want to end. A funny and action-filled story, Onyx takes the reader away. A story that will entertain you and fill-full your every Daemon fantasy, Onyx is fantastic!
