Rise of the dragons
(Juvenile Book)

Once our world was full of dragons who lived in harmony with humans. Dragons counseled kings and queens. They fought in human battles. And they gave humans the most precious gift of all: magic. But after a group of rogue dragons, the Raptors, tried to take over Earth, all dragons were banished to another realm. Most humans forgot about the dragons, claiming they never existed. Eleven-year-old Sirin knows the truth -- she grew up with stories passed down through the generations. However, when her mother falls ill, even Sirin has trouble believing in magic ... until she sees a mysterious streak of silver in the night sky. Sirin becomes the first child to lock with a dragon in centuries -- forming a deep friendship unlike anything she's ever imagined. But Sirin learns that not all dragons returned with good intentions, and soon she finds herself at the center of a battle between the dragons who want to protect the humans ... and those who want to destroy them.
