You’ve finished Iron Flame, and you’re ready to spend another evening back in Empyrean. Onyx Storm — Standard Hardcover is the featured physical reading copy for continuing the series and adding the next main novel to your shelf.

Fit note: The main-novel order is Fourth Wing, Iron Flame, then Onyx Storm. This is the standard hardcover, with no signed or decorative-edition features assumed. Use the author’s content notes where relevant to a gift.

A reading copy or a collector search?

A standard hardcover gives you the book to settle into and a physical volume to keep afterward. If continuing the story is what you’re looking forward to, that is a clear shopping path. A signature or decorative edge treatment is a separate edition-specific search.

Choose where the story will meet you

Print suits the reading chair, the bedside stack, or a book you can lend. Digital and audio are format alternatives for readers who prefer carrying a device or listening. The featured offer here is the standard hardcover, so the product page leads to that particular copy.

For an existing fan, the next volume can be a thoughtful gift because it picks up an interest they already have. Knowing which book they’ve reached settles the main question. Our book-gift guide offers another path when you’re buying for a reader with a different taste.
