Atlantica: Amulet of the Guardian (Part 1)

This is part 1 of the book: Atlantica: Amulet of the Guardian
The Atlantica Territories - a loosely held group of city states controlled by the human race - is on the brink of total annihilation. To the south, a sinister nation known as the Dark Empire has recently discovered an ancient art to tip the balance of power - the ability to control and fly dragons. Now besieged by an aerial bombardment against which they have little defense, the Atlantican people struggle to survive. However, one teenage girl holds the key to their possible salvation. She is known as Loki. Having already lost her family to the war, Loki becomes a refugee and flees the fighting for sanctuary in the Elf Kingdom. Loki's father worked as a historian and studied the secret lore concerning the Amulet of the Guardian. It was said the amulet possessed divine powers that could summon a super-natural being - a Guardian - to the planet. Loki believes the Guardian could save her world. It is one orphan girl's determination that drives her to complete the work of her father...to find the amulet...to summon a Guardian...and to save her people from the Dark Empire once and for all.
