This is an excellent but not comprehensive collection of his works. Its well worth downloading to your kindle so you can read any of the 27 Verne novels included (He wrote 54 novels plus other short stories; but his most famous are here). The translations from French to English are mixed between newer translations and old - this is important because unfortunately some of the older (Victorian) translations of Verne's works were not faithful to the original texts, with certain translators removing elements that were perceived as critical of the British Empire (though Verne was certainly not Anti-British, and some of his most popular works feature British heros). The books appear to be, for the most part, a mix of newer translations and the better older translations.
My only (very minor) gripe with this ebook is when you use your Kindle's "Go to..." and try to select the "Table of Contents", the button is greyed out. This is the publisher's fault as they've created the table of contents in the wrong way. It DOES exist however; you just need to go to the "Cover" and then turn a couple of pages; it has a comprehensive set of links to each book and then each chapter as needed.
So 4.5/5 for the books and translations, and lost half a star for one minor annoyance. This is a well presented and organised collection, and for the tiny amount asked, well worth it; certainly much easier than collecting the works individually for free (and legally) from the internet. Highly recommended.
