I have finished reading this, if I didn't know better I would say it was Defoe who wrote the whole thing. Seriously, you captured his voice perfectly. Your variation on the story was well crafted and set me down on a Carib island 300+ years in the past.
The lycanthrope aspect was very interesting since he describes it all with the, "seeing things through a smoky lens," effect and his sometime feeling of helplessness at events. I also found the way Crusoe and his "beast" grew more in synch the longer he was on the island. I also found it interesting that the island affected him differently than it did the other European types. The Friday character was something else, I liked the sword scene even more since you did it in Legos. I'm going to have to dig out some more words without giving spoilers - I always hate when reviewers do that. I'll be pimping this quite a bit more to my InfernalNet friends and aquaintances.
