Eelco Bruinvis, seventh son of a seventh son, loses both his parents and leaves the job-to-job dallying behind him. He chooses to develop his magical powers. The plan to become a magician seems to fall apart when his grandfather sabotages his plans. But Eelco is determined and goes to Romania, looking for a new magic teacher. What he finds there, he could not have predicted... Chased by ferocious werewolves, Eelco climbs a deserted hill. What begins as a desperate attempt to escape ends with a fall into a mysterious hole. This is no ordinary trap: it leads him to three different worlds. In the present, he must survive among dragons and dwarves, including the feared silver dragon Cryf. Thanks to his ingenuity, he wins a magic contest, comes into possession of a magic ring and takes revenge on his grandfather. In the past, Eelco saves a tribe from destruction, becomes a hero, marries and starts a family. The magic ring comes his way for the first time. But homesickness for his own time continues to gnaw at him, and when he returns, the present turns out not to be what he expected. Coffee and the internet no longer interest him: he wants to return to his family, the peace and quiet. In the future, adventures await him in devastated Europe on his way to a magical community in cold Iceland. He saves Sofia from murderers and meets the magical human beings. He meets the dragon Cryf again and finds the magic ring. With the help of a giant river snake, he defeats a group of mutants. Finally, he starts a new life on the Faroe Islands. Cryf tells him the truth about the dangers of a seventh son.
