[This review pertains only to the set of 34 being sold for $1.99, NOT to the set of 38 from Acheron (to which this review is erroneously attached) which has sound translations but is unreadable due to its light gray font--at least on a Kindle Keyboard 3.4.]
This is generally a good set with one major exception. The translation of "Journey to the Center of the Earth" is the bogus one with Professor Hardwigg rather than Liedenbrock and much else that is not Verne. In fact, it isn't really a translation at all, but a total rewrite by someone who thought he could "improve" what Verne wrote, even changing the names of the characters. That's the bad news.
The good news is that the TOC exists and works fine. Also, this set includes a title not included in most of the other large Verne collections: "The Adventures of 3 Englishmen and 3 Russians in South Africa" (also known by several other titles: "Meridiana," "Measuring a Meridian," and "Adventures in the Land of the Behemoth"). While not on a par with Verne's best-known works, it is still worth reading--and this set has it. But of the two works, I would rather have the correct version of "Journey to the Center of the Earth" (also known as "Journey into the Interior of the Earth," under which title you usually get the correct translation).
There are many large Verne sets available for under three dollars, including one by Delphi that has virtually EVERYTHING he ever wrote. So it pays to really shop around, sample, and compare before purchasing.
