You Finished Fourth Wing / Empyrean.
What Now?

A mortal girl is taken to a faerie land — dangerous, beautiful, and governed by rules she doesn't understand. The romance is slow, the danger is real.

The exact same romantasy DNA as Empyrean: a fierce heroine, a dangerous love interest, a world that punishes weakness. ACOTAR's world-building is richer; the romance hits just as hard.

Poppy has lived her whole life under strict rules as the Maiden. Then Hawke arrives as her new guard, and everything begins to unravel.

The forbidden-romance tension of Empyrean at its most concentrated. Armentrout's pacing is relentless and the revelation structure (who characters really are, what's really at stake) mirrors Yarros's playbook.

An ancient evil is returning. A handful of people are rediscovering powers that were thought lost. The storms that scour this world shape everything — ecology, architecture, war.

The military academy → active warfront arc of Empyrean at full epic scale. Sanderson's magic systems are as internally consistent as Yarros's dragon-bond rules, and the cast is just as large.

A young soldier discovers she has a rare power that makes her the most important person in the world — and the property of the most dangerous man in it.

The war college setting, the dangerous mentor figure, and the heroine who doesn't realise her own power until it's almost too late. Bardugo's world is darker and the politics more complex.

Mariko's convoy is ambushed on the way to her arranged marriage. To find the truth, she disguises herself as a boy and infiltrates the gang responsible.

For readers who loved Violet's determination and competence under impossible conditions. Ahdieh's prose is lush and the mystery plot rewards attention.

The third book in the Empyrean series continues Violet's story into the wider war.

If you've only read Fourth Wing and Iron Flame, the third book is here. The series is ongoing.

Kvothe — the most notorious wizard of his age — tells his own story from the beginning. He was once the most brilliant student at the Arcanum. He is now hiding from his own legend.

For the readers who loved Violet's intelligence and the school-of-dangerous-magic setting. Rothfuss's prose is more literary; the magic system is as meticulously constructed as dragon-bonding.
