Hummingbirds

The adorable little avians we know as hummingbirds are a far cry from the nasty thing that attacks Carley Richards as she hikes in the Colorado wilderness. The wounds appear minor, but the after-effects are devastating, as Carley and John Richards are rushed to a secret government hospital complex to face the effects of this attack - and possibly Carley's death. This alien creature's insidious purpose is revealed in the taut story of a young couple's unlucky brush with fate, and the life-changing consequence which will test their commitment to each other.

(This is a short story.)
