Edinburgh is a city filled with magical creatures. No one can see them... until Ramya Knox. As she is pulled into her family's world of secrets and spells, Ramya sets out to discover the truth behind the Hidden Folk with only three words of warning from her grandfather: Beware the Sirens. Plunged into an adventure that will change everything, Ramya is about to learn that there is more to her powers than she ever imagined.

Stuck in Loch Ness while Edinburgh falls under the control of a terrifyingly powerful Siren, Ramya Knox is frustrated. She's supposed to be learning magic from her Aunt Opal, but that isn't going as smoothly as she'd hoped. As she pushes to rescue her Hidden Folk friends in the city, long-buried secrets come to light and legends come to life. Ramya knows she's different; she knows she's a witch. But now she must learn the true meaning of her powers... before all she loves is lost
