The Stone Light, The Dark Reflections: Book #2: Book Two

Deadly magic and malice threaten Merle and Serafin in this breathtaking sequel to The Water Mirror.
Merle -- carrying the mysterious Flowing Queen within her -- and Vermithrax, the winged stone lion, are flying into Hell. They are looking for help in freeing Venice from the invading Egyptian pharaoh and his mummy warriors. But some truly nightmarish surprises await them as they travel to the center of Hell and encounter its sinister ruler -- Lord Light.
Serafin remains in Venice, where the gorgeous sphinx Lalapeya recruits him into a plot to assassinate the pharaoh. But does Lalapeya really believe a small group of boys can outwit the cunning sphinx commanders and kill the most powerful man on earth? Betrayal lurks in unexpected places, and startling revelations occur as Merle and Serafin learn that evil takes many shapes in the astonishing world of Dark Reflections.
