A mysterious key, six watchful ravens, and the legend of the Tower of London-will Mercer escape through Traitor's Gate before it's too late?
When Mercer discovers a strange key in the beach house attic, he has no idea it will whisk him back in time to one of the most complex places in history - the Tower of London.
Inside its cold stone walls, Mercer meets two boys with a dangerous secret: they are princes held against their will, and tomorrow one of them is to be crowned king. But Prince Edward doesn't want a crown - he wants freedom.
With guards closing in and ravens circling overhead, Mercer and the princes must rely on courage, quick thinking, and the mysterious key to escape before dawn. From torchlit stairways to the dark waters of Traitor's Gate, every step is more perilous than the last.
Can three boys - and six watchful ravens - outwit the Tower's guards and claim their freedom? Or will the legend of the Tower keep them locked inside forever?
