Separated the Dutch 2-in-1 book from the English editions of book 1.
Added it to the series: https://www.goodreads.com/series/1572...

Are you sure this isbn and format belong together?
Both Dutch Royal Library and the publisher have 9789036071277 for the paperback edition. The publisher has 9789402526332 for the ebook edition.
(9789036071277 was added as ebook edition.)

[Mary]

Oh it should be the ebook edition, thus 9789402526332. Sorry for the mix up!

[Arenda]

We don't changes isbn's for existing editions. I've corrected the format for the existing edition to paperback and added a new ebook edition: https://www.goodreads.com/book/show/3...

Sory for the extra work and thanks for the correction
