Sirin, Allie, and Joss have joined forces with the legendary silver dragon Lysander, the only creature capable of opening portals
between the two worlds. But the powerful Lennix clan is following the children's every move and will stop at nothing to capture
Lysander. After generations of plotting, the Lennixes-and their bloodthirsty dragon allies, the Raptors-are terrifyingly close to
establishing a brutal dragon regime on Earth, just like they did centuries ago.
Now, it's up to Allie, Joss, and Sirin to protect Lysander while searching for a secret source of lost dragon magic, the only force
powerful enough to stop the Raptor. But when their search takes them to one of the largest cities on Earth, the new friends must
decide what's more important: finding the missing treasure or guarding the most important secret in the world-that dragons have
returned to Earth. . . and not all of them have good intentions.
