Common questions

What order should I read a series in?

Start with publication order, the order the books first came out. When a series also has a story order that differs, the series page shows both and says why, so you can choose.

Which book should I start with?

Look for the Start here marker. It sits on the first book of the main list, unless the author's own page recommends a different first book, and the reason is printed beside it. It is not a ranking or a review.

What if an order looks wrong?

Tap Report a problem under the list and say which book looks out of place. No account or email is needed. Each report is checked against the sources, and the page is corrected if the report is right.

Does this site earn money from the links?

It can. If you buy through a store link, this site may earn a small amount. That never changes the list: which books are listed, their order, and the fixed order of the store buttons stay the same.

Where do these facts come from?

One page shows the sources and how the facts are checked.
