One book or the whole series: where to start translating
Start with one book, unless you already have evidence that the series works in that language. Translating a whole series multiplies the cost and the time before you have seen a single paying reader, and that is the bet that is hardest to recover from.
But there is another side to this, and it is real: series readers read in a row, and a series cut off in the middle loses them.
Why translating everything is tempting
A reader who has just finished book one and loved it is at exactly the moment when they are ready to buy the next. If the next does not exist in their language, that moment passes.
This is especially true in genres where people devour series — thriller, fantasy, romance. There a single book is almost half a product.
So the logic of "translate it all and open the tap" sounds right. The problem is that it is only right if the readers actually turn up.
Why you still start with one
Because a book in a new language starts from zero. No reviews, no previous readers, and nobody knows your name.
Three translated books that fail to find an audience are not three times the failure — they are three times the cost of the same failure. One book that fails to find an audience teaches you the same thing at a third of the price.
And there is another reason, less often discussed: the first book teaches you how your book sounds in the new language. The names, the humour, the rhythm, the way the characters speak. You carry those lessons into the next books, and they come out better.
What you tell the reader in the meantime
This is the part most authors miss.
If you are releasing only the first book, say so in the book description: that this is a series, and that the next one is coming. A reader who knows in advance waits. A reader who finds out alone feels tricked, and writes about it.
And do not promise a date you are not sure of. "The sequel will be translated later this year" beats a precise date that slips.
What Amazon allows technically
You can set up a series in the store and give it a reading order. According to Amazon, you do not need every book in the series to be finished in order to create one, and the series page appears within 72 hours of it having live titles.
Which means you can open a series with a single book and add titles as they are translated. The reader sees a structure rather than one stray book.
What happens to the cost when you multiply
One more practical point: translating a series is not only multiplied in cost by the number of books, but multiplied in your own work too.
Each book needs its own cover, its own description, your own check, and an update to the language so that it stays consistent across the series. An author who orders three books at once discovers they have to read and approve three books at once, in a language they usually cannot read.
So even someone who has decided to translate a whole series does well to split it into stages rather than sending everything at once.
So what is the recommended order
Translate book one. Give it a few real months with some marketing. Look at two things: is it selling at any rate at all, and do the reviews talk about the story rather than the language?
If both are fine, translate the second, and then consider doing the rest in a row so as not to break the run for readers.
And if not — you stopped after one book, which is exactly what you intended. Before anything else it is worth translating a sample chapter to hear how the book sounds, and considering which translation route suits your kind of book.
Frequently asked questions
Should you translate the whole series at once?
Only if you already have a sign that the series works in that language. Otherwise you are paying for books nobody may read. The careful route is one book, then a decision.
What is the risk of translating only the first book?
A reader who enjoys it and finds the sequel does not exist in their language is disappointed, and sometimes writes that in a review. So say in the book description that the next one is coming, and then keep to it.
How long before you know whether it works?
You need a few months of real sales and a few reviews. A book in a new language starts with no reputation, and two weeks tell you nothing.
Can you keep the series order in the store?
Yes. At Amazon you can set up a series and fix the reading order, and you do not need all the books to be ready in order to open one.
