The Memory of Idhún is a fantasy and adventure trilogy written by the Spanish author Laura Gallego,[1] writer of other books like Finis Mundi or Crónicas de la Torre.
The books tell the story of a fantastic chain of events that will affect two worlds: Earth and Idhún.
There is also a seventh god, enemy of the rest, which created the cold-blooded Szish and the semi-divine sheks, which are winged snakes.
However, a powerful necromancer, Ashran, allied with divine magic, caused a conjunction of the three suns and moons of Idhún, and used its energy to kill all dragons and unicorns so the sheks could come back and, helped by the Szish, rule the world and the warm-blooded races.
Jack and Victoria, both born on Earth, join the Resistance (which consists only of Shail, a young wizard, and Alsan of Vanissar, a warrior and prince) and try to stop him.
Meanwhile, the unicorns randomly spread magic through the world, touching people with their horns in order to make them semi-wizards or wizards.
The Resistance will find new and powerful enemies as the story goes on, such as the beautiful fairy Gerde, who will have an important role in the last book.
Idhún has essential characteristics of the Middle Ages, such as animal transport and feudal kingdoms.
At first, there were six books: Búsqueda (search), Revelación (revelation), Despertar (awakening), Predestinación (predestination), Convulsión (convulsion) and Génesis (genesis).
However, the author and the publisher agreed to merge every two titles into one book, and give the three of them a similar length (28 chapters, a preface and an epilogue).
