The truth
Alot of reviews are saying the Edgar Rice Burroughs did not actually write "John Carter and the Giant of Mars". The truth is that he did. This is what happened and what causes confusion: a childrens publisher wanted a short version of a Edgar Rice Burroughs' novel. Mr. Burroughs was concerned that he could not keep it short enough for the publisher so he asked his son to help craft a shorter story. At the same time, Amazing Stories asked Edgar Rice Burroughs for another Mars novel. A full lenght one to serialize. Edgar took the short story and stretched it to a full novel. This is confirmed by several sources and by Edgar Rice Burroughs estate. It explains why some of the novel strays from the rest of the series. So, yes his son was involved, but it is wrong to say that Edgar Rice Burroughs did not write it. He did. Especially the novel version.Anyway, all of the Mars books are exciting and I recomend all the books in the series.
