If you crave dragonriders, deadly trials, and devastating slow burns — this list will ruin you in the best way.

There’s a kind of ache only certain books can leave behind — the kind that lingers after the final page, refusing to let go. Fourth Wing did that. So did Onyx Storm. Maybe it was the slow-burn romance, the knife’s-edge tension, or the feeling of being chosen when you thought you were invisible.

I remember finishing them in the dead of night — heart racing, mind spiraling. Craving not just another fantasy, but something that would leave me breathless. That same pulse of magic, danger, and forbidden longing had to be there. If you know that hunger — if you’re chasing the next ride-or-die series — this list is for you.
