  1. Harry Potter: A Journey Through Potions and Herbology

Its description says:

“Potions have been made for thousands of years – associated with bubbling pots and mysterious ingredients. They have been brewed to make medicines, drugs and poisons.”

“Plants have also been important components of medicines as much as myth-making and magic. A source of danger as well as a means of overcoming obstacles, Herbology was a subject which had a major bearing on Harry’s key decisions and mistakes in the wizarding world.”

  1. Harry Potter: A Journey Through Divination and Astronomy

Though Divination and Astronomy weren’t Harry’s favorite Hogwarts courses, there’s plenty of historical backing for the subjects’ importance at the school. And this eBook dives right into it.

The description reads:

“From the use of bones and shells thousands of years ago to peering into teacups in the parlors of Victorian England, for millennia, people have strived to see what fate and fortune holds.”

“Trying to read our destinies, the study of the night sky has fascinated people for centuries, from the star atlases of ancient China to the celestial globes of 17th-century Venice.”

  1. Harry Potter: A Journey Through Care of Magical Creatures

If you share Hagrid’s love of magical creatures, this is the book for you

The description states:

“In the past, naturalists and explorers traveled the globe to encounter weird and wonderful creatures that enhanced our knowledge of the world and pushed forward the development of science.”

“Nevertheless, it seems part of human nature to want to believe in the unbelievable: from the bestiaries and cabinets of curiosities of the medieval period onwards. We think that truth and myth are easily distinguished today, but magical creatures and the stories around them continue to fascinate us — and they are as central to the Harry Potter stories as Harry, Hermione and Ron.”

And many people are excited about the new Harry Potter books on social media.

The eBooks are initially available in English, French, Italian and German.
