Riwenne & the Mechanical Beasts — Kristen S. Walker

In a utopian floating city, Riwenne dreams of serving the gods as a priestess. Then she gets a message from the sea goddess urging her to become a warrior. Mechanical beasts are attacking innocent people on the streets at night. Armed with the power of the goddess, Riwenne must learn to fight. But if she wants to save the city, she will need to decide who is a friend and who is an enemy--and the wrong choice could have deadly consequences.
