From a Barren Seed Grown

The Colony of Edge will never be the same.
When Ash Morgan returns after a long time away, she finds she hardly recognizes the place she once called home. Black towers stretch to the sky, strangers wander the streets, and odd smells permeate the very stones.
Monsters roam the streets.
After a terrible attack, Ash must determine what strange monster lurks among the city's newest inhabitants. How is it connected to all the changes happening in the rapidly growing colony? More importantly, can she determine when the monsters attack next?
And why?
