If my memory serves well, this was the last book of The Lux series by the author. Jennifer Armentrout is a #1 NYT best-selling YA author. My wife and I translated at least 10 of her books into Turkish in the last six or seven years. I personally prefer Armentrout’s other well-known series, The Covenant. The English version of Opposition contains the prequel (Shadows) and I remember translating it into Turkish but I am not sure whether it was included within the Turkish translation or not.

By the way, all the titles in this series start with the letter “O.” (Onyx, Opal, Obsidian, Origin, Opposition)

Anyway, here comes the Amazon.co.uk description:

Opposition

Katy knows the world changed the night the Luxen came. She can’t believe Daemon stood by as his kind threatened to obliterate every last human and hybrid on Earth. But the lines between good and bad have blurred.

Daemon will do anything to save those he loves, even if it means betrayal. But when it quickly becomes impossible to tell friend from foe, and the world is crumbling around them, they may lose everything to ensure the survival of their friends…and mankind.

Shadows

The last thing Dawson Black expected was Bethany Williams. To him, human girls are…well, fun. But since the Luxen have to keep their true identities a secret, falling for one would be insane. Dangerous.

Bethany can’t deny the immediate connection between her and Dawson. And even though boys aren’t a complication she wants, whenever they lock eyes, she’s drawn in. Captivated.

Dawson can’t stop risking everything for one human girl. Or stop a fate that is as unavoidable as love itself.
