Publisher's blurb: A foreign jungle glistens phosphorescently in the dim light, under a pale star. Purple ferns brush against booted feet, and strange calls echo out across the alien planet. Red trees loom tall, and the cloying scent of iron stifles the nostrils. There is so much in the environment, that the creature’s don’t hold it in their blood—instead having clear or copper based (blue) nutrients flowing through their veins.
