Like Timothy M., I have a soft spot for stories where nature takes back over from man; though I would not refer to humans as a disease, rather the societies we have thus far created have a tendency to become toxic. Truthfully man's dominance of nature is tenuous at best.
Well there is drama to be sure, as well a suspense. Mikiesboy, you truly are an accomplished author. Also the ending was perfect.
Normally I shy away from gay themed science fiction, often it is very poorly written. But this is perfect--a story of love and struggle and love in a world "After the Before".
