The three part novel from 1918 should be classified as science fiction, but in our modern era it feels a bit more like fantasy. The creator of Tarzan brings us a very imaginative tale of evolution, mystery, (casual racism and sexism,) and action that is his trademark. A group of Brits, Americans, and Germans come across a hidden island filled with prehistoric people and animals and all the dangers such a place entails. There is certainly a lot to enjoy with this story, but I realize that I wish I read it as a younger man, when I could get more wrapped up in the excitement and less on the critique. As is, I was annoyed that certain parts (such as the trip to the island) are given dominance when I want to hear about others (such as the island!), and the ending of the third part kind of undermines major events of the previous two. To give credit where due, the novel is heavily influenced by other sci-fi works of almost the same name. Part of me wanted to read this as I have a vague recollection of watching on TV the 1975 movie version of this written in part by Michael Moorcock, which fascinated me even if I don't remember much of it. I doubt I'll ever see that movie as I'm sure to hate it and it is (perhaps) better to have the dream.
