Would You Defy Your Destiny to Protect your Family? While seeking information on the location of their missing family members, Miranda and Justin McAdelind discover they are part of a much larger, more complicated, and dangerous world than they ever imagined possible. But after an attack at Thunderbird Ranch exposes just how vulnerable they are, Miranda and Justin are forced to retreat to a secret valley deep in the Rocky Mountains-a valley that their mother's people have kept hidden and protected for millennia. However, they quickly discover that no place is safe for long when two powerful monsters appear and threaten to destroy everything. Their only hope is to embark on the sacred mission of the Dragon Rider and discover a way to protect themselves and their family from this new threat before all is lost. The Dragon Riders, an upper middle-grade modern fantasy novel, is the second book in the Cowboys and Dragons series by Anthony A. Kerr. If you like Percy Jackson and the Last Olympians, The Kane Chronicles, Fablehaven and the Harry Potter series, then you'll love The Dragon Riders.
