Marvel's What If...? (Madeleine Roux) Books in Order

Marvel's What If...? stories run on a simple, flexible idea: change one key event, and suddenly a familiar world starts making very unfamiliar choices. In prose, that setup gives writers room to keep the recognisable characters while pushing them into a different moral weather. Madeleine Roux's corner of that line begins with What If... Loki Was Worthy?, which tells you right away what kind of alternate-universe game she is playing.

Thor is dead.

Not in some distant, abstract way either. His death follows a prank from Loki that spins badly out of control, which means the whole book begins with guilt already baked into it. Loki is banished to Earth, stripped of the easy status games of Asgard, and forced to sit with the consequences of being clever without being careful. That is a good Roux setup. She likes characters who are not ready to admit how much damage they have done.

Redemption is the real hook.

The book's version of Loki is still sarcastic and proud, but the story keeps pushing him toward responsibility. Valkyrie arrives carrying Thor's final request, to find Jane Foster and make sure Mjolnir reaches the right hands, and that quest becomes the spine of the novel. At the same time, grief on Earth is curdling into something dangerous. Tony Stark, furious at what Asgardian power has cost the world, starts turning that anger into weapons. So the story is not only asking whether Loki can change. It is also asking what other people become when loss convinces them vengeance is the only sensible answer.

That makes this a good fit for the wider What If...? idea. The point is not just novelty. The point is seeing what a changed event reveals about character. If Loki is cut off from his old excuses, who is left? If worthiness is not a family title but a moral test, what does he do when nobody wants to believe he can pass it?

You do not need a giant continuity spreadsheet to enjoy that. It helps to know the broad shapes of Thor, Loki, Jane Foster, Valkyrie, and Tony Stark, but the emotional line is clean. Exile, guilt, unfinished duty, and the possibility of earning trust are easy things to track even when the world around them is full of gods and armor and impossible weapons.

So if you are looking at Madeleine Roux's What If...? shelf, expect a Marvel story built around one hard turn and the fallout that follows. Expect familiar names in altered positions, fast-moving consequences, and a version of Loki who has to decide whether being underestimated is still useful once the whole world needs an answer from him.
