Scorpion Dawn: a novella of gaslight and magic - Hellion House Steampunk Series, #2

When the prey becomes the hunter . Miranda Fletcher lives in a glittering world of aeronauts and artists, dance cards and dandies, but terror lurks outside the city walls. The countryside is infested with hungry abominations called the Unseen, and a single crack in the capital's defenses invites disaster. Then Miranda witnesses a murder and learns the walls aren't as secure as their magical protectors claim.
But despite a string of bloody crimes, no one is foolhardy enough to question the mages, much less battle monsters at the gate. Except Miranda. When tragedy shatters her home, she'll risk everything to get answers-and vengeance. Even death. Sometimes the smallest creature carries the deadliest sting.
