Magic Calls (Echoes #1)

A war is brewing beneath the sidewalks of Washington, DC . . . and Molly just sang her way into the middle of it.
Molly doesn’t know there’s anything unusual about her voice—she only knows that performing with her band makes her happier than anything else in the world.
But everything changes on the night that Molly does more than just entertain her audience—she accidentally entrances them, and narrowly avoids setting off a riot.
Now, she’s being hunted by a mysterious group that believes she is descended from the Sirens—and that she’s unworthy of the power she possesses.
To survive, she must plunge into a secret world of human-Siren hybrids, where there’s no easy way to know who to trust.
With time running out, Molly must learn to wield the power inside her, before the hunters can silence her forever.
