Columbine's Tale by Rachel Nightingale

For three hundred years the travelling actors of Litonya roamed the land entertaining crowds, but secretly leaving devastation in their wake. Is Mina the only person with the power to stop them?

In the ethereal otherworld of Tarya, Mina begins to master the rare, inexplicable powers  attached to her gift for storytelling. She discovers she can touch dreams, influence the real world, and perhaps find out who is manipulating Tarya for dark purposes. In the waking world Mina is on the run, beset by divided loyalties between the travellers, and caught between two men she could love and a brother who desperately needs her help.
