The unputdownable third book in the beloved LUX series from bestselling author, Jennifer L. Armentrout!

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 HE CAN'T PROTECT EVERYONE.

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 of. 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.
