Would you like to know more about the play or the Harry Potter series in general?

On the Hogwarts Express, Albus meets Scorpius Malfoy, the son of Draco Malfoy, and they quickly become friends. However, their friendship is put to the test when they become entangled in a mysterious plot involving a cursed child and a dark wizard from the past.

Here's a brief summary:

As the story unfolds, Albus and Scorpius must navigate the challenges of adolescence, friendships, and the complexities of their family's histories. Along the way, they encounter a range of characters, including a younger Hermione Granger and Ron Weasley, who offer guidance and support.

I'm assuming you're referring to the story of "Harry Potter and the Cursed Child," a two-part stage play written by Jack Thorne, based on an original story by J.K. Rowling, Jack Thorne, and John Tiffany.

The play explores themes of identity, family, loyalty, and the power of love and friendship to overcome adversity.

As for the e-book format and VK (which I assume refers to a social media platform or online community), I couldn't find any information on a specific "Harry Potter and the Cursed Child Epub Vk" edition. However, the play's script has been published in book form and is widely available in e-book formats, including EPUB.

The play focuses on the adventures of Albus Severus Potter, Harry's youngest son, who is about to start his first year at Hogwarts School of Witchcraft and Wizardry. Albus is struggling with the weight of his family's legacy and the pressure of living up to his father's expectations.
