Brother and sister dragonology students Daniel and Beatrice Cook are looking forward to returning to their studies with Dr. Ernest Drake and Erasmus, their dragon tutor. But when they discover that the evil dragonologist Alexandra Gorynytchka is searching for the fearsome Hammer of the Dragons - an ancient weapon that can kill hundreds of dragons in a single stroke - Dr. Drake and the children pursue her all the way to the Lost Island of the Dragons, where she is amassing an army of enslaved dragons. There they learn of the Dragon Prophecy, according to which the return of the Hammer of the Dragons can be stopped only by two children "wise beyond their years in the ways of dragons." Could the prophecy point to Daniel and Beatrice? And can they save dragonkind before it's too late?
Daniel Cook and his sister, Beatrice, are thrilled to be studying dragonology with Dr. Ernest Drake ;- ; they're even awaiting the hatching of a dragon's egg in their care! But all is not well: there are rumors of a deadly plague affecting dragons around the world. Could dark dragonologist Alexandra Gorynytchka be behind the mysterious illness? The siblings soon discover that the secret to curing the dragons might be found in the Liber Draconis, a diary written by a wise dragon ages ago ;- ;if only they could decipher it! So they set off (with their mischievous dragon chick in tow) on the Dragon Express, riding one dragon after another in a race to bring Liber Draconis ; - ; and a cure ;- ;to Dr. Drake before it's too late.
Daniel and Beatrice Cook, along with their parents and their dragon chick, Torcher, are getting ready to open an orphan dragon sanctuary near Castle Drake in St. Leonard's Forest. But then Dr. Drake brings news that several dragon members of the Society of Dragons have been attacked and it looks to be the work of the Dragonsbane Knights, a secret society of dragon killers that was thought to have been eradicated centuries ago. If Dragonsbane is resurfacing, then no dragons in Britain are safe! When Torcher is kidnapped, Daniel and Beatrice are convinced that Dragonsbane is behind it, and, with the help of the Guardian Dragon's apprentice ;- ;an adolescent half-European, half-frost dragon named Erasmus ;- ;they race to bring Torcher home before it's too late.
The precious Dragon's Eye jewel has the power to reflect the true Dragon Master, the keeper of the fates of all dragons. When evil dragonologist Ignatius Crook sets his sights on the jewel, Dr. Ernest Drake must put a stop to his criminal plans.
Luckily Dr. Drake has help - "¯his two newest students, twelve-year-old Daniel and his sister, Beatrice, have carefully studied dragonology and are ready to use their knowledge to find the jewel. But only true dragonologists will be able to win this race against time.
