'Dumped in the River Charon, hunted by an acursed river creature and betrayed by the wicked Matron Pluckrose, Tensy Farlow is in mortal danger. She has no parents. Worse still, she has no guardian angel.
'When she is thrown into the Home for Mislaid Children - a gloomy orphanage where ravens attack, Watchers hover over your bed, and even the angels cannot be trusted - it seems that all hope is lost.
'Yet could it be that a plucky, flame-haired orphan with a mysterious past is precisely what this dark world needs?' (From the publisher's website.)
