Katy expected the hardest part of moving to a new town would be making friends and starting her book blog. Then she meets her neighbours – a pair of arrogant, impossibly beautiful siblings who act like the world bends around them. Daemon, in particular, has a gift for making insults sound like compliments. But beneath his smirk is a secret: he isn’t human. He is Luxen – a being of living light, hiding on Earth from an enemy that wants to burn everything he cares about.
“Obsidian” launches the five-book Lux series with a collision of attraction and danger. Katy doesn’t want to be a damsel, and Daemon doesn’t want to care about anyone who could get him killed. Their chemistry is electric – literally. Every moment together risks exposing the truth to those hunting the Luxen. What happens when getting close to someone could destroy not just your heart, but your entire species?
Armentrout blends small-town normalcy with high-stakes sci-fi. Homework, blog tours and snarky banter crash into firefights, conspiracies and lights that scorch the night sky. Friendship becomes a shield; trust becomes a gamble with consequences measured in lives, not feelings. There’s humour and heat, but also a question pulsing underneath: who decides whether someone gets to belong?
By the time the series reaches its climax, battles aren’t only against the enemy outside – but against fear, prejudice and the belief that ordinary humans don’t matter. Katy and Daemon must decide if choosing each other is worth the risks that could remake the world.
The Lux books deliver thrills wrapped in sharp dialogue and vulnerable moments. Readers get the rush of first love with the weight of choices no teenager should face. And at the core is a promise that shines through every page: light can be dangerous – but it can also be the way home.
