Listen! For I sing of Owen Thorskard: valiant of heart, hopeless at algebra, last in a long line of legendary dragon slayers. Though he had few years and was not built for football, he stood between the town of Trondheim and creatures that threatened its survival. There have always been dragons. As far back as history is told, men and women have fought them, loyally defending their villages. Dragon slaying was a proud tradition. But dragons and humans have one thing in common: an insatiable appetite for fossil fuels. From the moment Henry Ford hired his first dragon slayer, no small town was safe. Dragon slayers flocked to cities, leaving more remote areas unprotected. Such was Trondheim's fate until Owen Thorskard arrived. At sixteen, with dragons advancing and his grades plummeting, Owen faced impossible odds—armed only with a sword, his legacy, and the classmate who agreed to be his bard. Listen! I am Siobhan McQuaid. I alone know the story of Owen, the story that changes everything. Listen!

The year is 1917. Following the sudden death of his Professor, a young man and his two companions are approached by a strange man who gives them a book to safeguard. This book, the Imaginarium Geographica, is the reason the Professor was killed, and now, they too are in mortal danger. Chased by the ferocious Wendigo, half-man half-werewolf creatures, the three companions seek refuge on a ship - a ship that leads them to the extraordinary lands of myth and legend mapped in the precious book they carry. As their adventure unfolds we learn that the friends are in fact C.S Lewis, J.R.R Tolkien and Charles Williams - and as they discover that events in the known world mirror those in the imaginary realm, they come to realise the importance of the Imaginarium Geographica , and if not protected, there will be no peace from the war that rages in our world.

John, Jack, and Charles (who met nine years ago when they became Caretakers of the Imaginarium Geographica, an atlas of all the lands we think of as imaginary) have come together again. Someone is kidnapping the children of the Archipelago of Dreams - and the legendary Dragonships, which can cross between the two worlds, have disappeared. Their search takes them from Sir James Barrie and Peter Pan, to Jason and the Argonauts, Medea, the Pied Piper of Hamelin, and much more! An inventive, magical adventure that will keep readers riveted.

Restoring the Archipelago of Dreams comes with a precious price in this final volume of the critically acclaimed Chronicles of the Imaginarium Geographica series. To save the world, Charles, the Grail Child Rose Dyson, and Edmund McGee must travel deep into the past to discover the identity of the mythical Architect of the Keep of Time. However, even if that tower can be restored, the Archipelago of Dreams is still missing. Somehow, the first Dragon must be found to restore the lands to what they once were. But fulfilling their mission may be giving the Echthroi exactly what they wanted all along… In this chilling conclusion to the critically acclaimed Chronicles of the Imaginarium Geographica series, the Caretakers will have to trust those who were once enemies, defeat the worst within themselves, and discover what may be the most important truth of all: where there is hope, and will, and courage, redemption is always possible.

The Caretakers of the Imaginarium Geographica are at war. The Imperial Cartological Society, led by Richard Burton, have collected all of the doors from the Keep of Time, and are building a new tower in our world at the request of an old enemy: The Winter King’s Shadow. He has a terrible weapon – The Spear of Destiny – that can be used to command the shadows of anyone it touches…including the protectors of the Archipelago, the dragons. With a ship called The Iron Dragon, the Shadow King regains passage to the Archipelago where he uses the power of the Spear and the portals of Time to enlist an unstoppable army of Dragon Shadows. And after the Archipelago falls, he intends to betray the Allies in our world – but not to align himself with the opposition. The Shadow King intends to use the turmoil of WWII to take over BOTH worlds. All the legendary Caretakers, past and present, come together on a great island in the northermost part of the Archipelago to decide the ultimate fate of the Imaginarium Geographica, as a terrible battle ravages the lands around them. And their only hope lies with a small group of companions who are on the quest for the broken sword Caliburn: the Grail Child Rose Dyson; her mechanical companion, the owl Archie; a mouse with an attitude; a dead Professor of Ancient Literature; and the mythical knight, Don Quixote. They must sail beyond the ends of the Archipelago in search of the sword, and the only being alive who can repair it: a scholar, who, once upon a time, was called Madoc.

Seven years after the events of The Shadow Dragons, John, Jack and Charles are finally able to return to their beloved Archipedlago of Dreams. But even as their return is celebrated by old friends, new concerns shadow the reunion, namely the threat of Echthroi, the primordial Shadow, but, perhaps even worse, the apparent splintering of Time itself. Now, the Caretakers must fight against their most fearsome enemy ever and attempt to restore Time. They must journey through a forgotten door from the destroyed Keep of Time in order to seek out the Dragon's Apprentice. If they fail, it will mean the end of both of the worlds. But success will carry its own price - a price that may be too high even for the Caretakers to bear.

As Owen and Siobhan begin their stint in the Oil Watch, they face military bureaucracy, a harsh environment, and yes, slaying dragons. The sequel to the critically acclaimed The Story of Owen.
