This story reminded me very much of my own first few stories, both style and substance. The ancient curse amid Mayan myth and legend is prime material for a tale of the weird, and I see all sorts of Weird Tales-esque influences in here. The story is told well and the narrative, through the medium of a journal, is interesting to read. I thought the ultimate ending didn't quite fit; the modern-style end didn't quite gel with the more classic-weird narrative that went before it.
I don't normally comment too much about spelling and grammar but I think it's worth pointing out here that, yes, there are various grammar, spelling and typo errors, but they are of a kind that do tend to appear in early pieces of writing. I imagine that, with more practice, these errors, and the incongruous ending, will iron themselves out in time.
In the main, this was pretty good, and it certainly bodes well for the future. In his introduction to this story Ian Brunner says it is his first try at distributing a story; I would say to Ian, keep on writing, you've got something there.
This is a three star story but I'm giving it an extra star for encouragement and goodwill.
