Peek Inside Opal

After everything, I’m no longer the same Katy. I’m different... And I’m not sure what that will mean in the end. When each step we take in discovering the truth puts us in the path of the secret organization responsible for torturing and testing alien hybrids, the more I realize there is no end to what I’m capable. The death of someone close still lingers, help comes from the most unlikely source, and friends will become the deadliest of enemies, but we won’t turn back. Even if the outcome will shatter our worlds forever.

No one is like Daemon Black.

When he set out to prove his feelings for me, he wasn’t fooling around. Doubting him isn’t something I’ll do again, and now that we’ve made it through the rough patches, well… There’s a lot of spontaneous combustion going on.

But even he can’t protect his family from the danger of trying to free those they love.

After everything, I’m no longer the same Katy. I’m different… And I’m not sure what that will mean in the end. When each step we take in discovering the truth puts us in the path of the secret organization responsible for torturing and testing hybrids, the more I realize there is no end to what I’m capable. The death of someone close still lingers, help comes from the most unlikely source, and friends will become the deadliest of enemies, but we won’t turn back. Even if the outcome will shatter our worlds forever.

Together we’re stronger…and they know it.

❝I love you, Katy. Always have. Always will.❞

I guess waiting until the 3rd book was worth it to love and cherish it so much. I guess disliking the first 2 and not really wanting to buy the rest, only now wanting to read the rest was worth it. I mean, JLA has done such a great job with all this.... ...more

Sigh. Guys, I decided not to do one of my 'normal' reviews and instead do a '20 reasons why' thingy. I just LOVE this book so much, I can't even write a proper review.

So here's 20 reasons why you should read OPAL: (not that you need a reason :P

This series has consumed me! I've never read so quick, I can't convey how much I've loved what I've read so far, I've been devouring the pages, and because sleep is overrated my time has been better spent reading/inhaling books 1&2 in record speeds!! I never read this quick!!

And I learned that sometimes when someone says something so devastatingly perfect, there isnt a need for a response. The words said it all.

By ♥ Rebecca ♥ March 26, 2016

I liked this about the same as Onyx. It had more romance, and an even sweeter and more dreamy Daemon, but less action. So it evens out in the end. The only action was the two escape attempts, which dont add up to many pages.

But I really appreciate all the romance, and the focus on Katy and Daemon... ...more

Noooooo!!! I hate how the book ended!! WHYYYYYY?????


In the beginning , this book was simply awesome ! I was having such a good time with Deamon and his crazy ego !

A slow, wry smile teased Daemons lips. "Simmer down, Kitten, before I have to get you a ball of yarn to play with."

Annoyance flared...

3.5 stars Were you expecting something else for this series? If I themed books 1 & 2 like this, I might as well continue the trend. I'll start off in the right order this time with Good Cop.

First of all, I want to take the time to express what a fils de pute, I think Biff (Blake) is. They help him out at the risk all of their lives and the connard betrays them.

Opal is the third book from the Lux series and by far the most complex in plot and characters.
From all the books from this series, this one was the most intense from my POV. It literally drags you through all the stages of feeling, like anger, grief, surprize, horror, love, sadness and SHOCK. Ya... ...more
