Donors. The entire cycle in one volume by Olya Zakis

A long time ago in a magical kingdom created by the mighty wizard Bars, every resident had their own wonderful gift, received from the Heart of Magic. And then magic disappeared. Three hundred years have passed since then, and suddenly the story that had become a fairy tale has a continuation. The heroes of the new story – Henry, Edward, Rose, and many others – must return the lost gifts, solve the most complex puzzles, unravel more than one web of intrigue, battle terrifying monsters, and outsmart the craftiest of villains. But will they have enough courage, determination, and kindness to save their beautiful fairy-tale world?
