If you love wicked kings, sexy bandits and sister stories that are full of heart, this is a must read’ Stephanie Garber, New York Times and Sunday Times bestselling author of Caraval -

‘Riotously funny, fast-paced and dripping with romance, TWIN CROWNS manages to deliver a tale as familiar and nostalgic in the way of childhood blankets and fireflies in jars, while at the same time wholly refreshing with its levity, charm and quirky tale of sisterhood rediscovered.
