Once our world was full of dragons who lived in harmony with humans, and gave them the most precious gift of all: magic. But after a rogue group, the Raptors, tried to take over Earth, all dragons were banished to another realm. Most humans forgot about them, claiming they never existed. Eleven year old Sirin knows the truth, through stories passed down the generations. When she sees a mysterious streak of silver in the night sky, she becomes the first child to lock with a dragon in centuries, forming a deep friendship unlike anything she has ever imagined. But she learns that not all dragons have good intentions, and soon finds herself at the centre of a battle between the dragons who want to protect the humans... and those who want to destroy them.
