Abril and Xalaquia have a lot in common. They have both recently turned sixteen. They both want to be the mistresses of their own destinies. And they are both about to see their lives change for ever. They are separated only by time and space: Tenochtitlan in the sixteenth century and Madrid in the twenty-first century. Two worlds in which the girls will be obliged to undertake - in the company of friends - a dangerous journey. Two journeys through magic and mystery which share one, ultimate quest: that of identity. And the answer may have something to do with the hidden truth of their names. Or with the need Abril and Xalaquia have to set the sky alight with their yearning to be. To be everything, and to be it now.
