In book two of this middle-grade fantasy trilogy, Ista Flit — a daring heroine with the magical ability to look like anyone she’s ever seen — must help her father escape from an enchanted trap.

In her first adventure, Ista Flit and her friends saved the town of Shelwich from a monstrous foe—but her father is still missing. 

She has a new clue though: a key, engraved with mysterious symbols, and a note saying “any door with a keyhole will do.”

This key transports Ista, Nat, and Ruby to Glass Island—where creatures Ista thought were mythical turn out to be very, very real. A sinister wraith haunts the reed-beds, and deviously seductive, fairy-like marsh spinners lure people in to dance at their revels—and never let them go.

Ista is sure her father must be trapped in the marsh spinner’s lair. She’s determined to devise a plan cunning enough to infiltrate the revels and rescue Pa.

When the tide is high and magic is at its peak, Ista and her friends will face off with the trickiest creatures imaginable. Can they win Ista’s father’s freedom? Or will the revels claim three new dancers forever…?

Magic, mystery, and monsters abound in this series opener about a girl with the rare magical ability to look like anyone she’s ever seen. Now in paperback!

In misty Shelwich, magic ebbs and flows with the tides, granting the citizens extraordinary abilities every time the river rises. But people are disappearing…and rumor has it they are being snatched by monsters.

Ista Flit doesn’t want to believe it. Not when her own father is missing. As she scours the city, searching for clues, a notorious thief finds her. Ista has a rare talent: she’s a face-changer, able to take on the appearance of anyone she’s seen, and Alexo could use a girl with her skill. Ista could use Alexo’s help in her search–if only she could trust him.

As more people vanish, Ista finds unexpected allies in Nat and Ruby, each searching for their own missing loved ones. These three determined kids will need to use all the Tidemagic they can summon, to find out what connects thieves, monsters, and the missing. But they have no idea what dangers await them in the hidden labyrinth of caverns deep benearth the city streets…
