Archie Green and the Curse of the Crow

Archie Green and his friends are trying to save magic. They were rewriting magical books, updating the spells, when suddenly black flame literally scorched their efforts. The adults confirmed - this dark flame is indeed black magic, and it is growing stronger. To stop it, they need to unravel the mystery of the legendary alchemist Fabian Gray. Archie has encountered this name before - a huge crow brought him Fabian's writing quill when the boy had just started practicing magic. And now someone is leaving messages for Archie and his friends, signed F.G. with a drawing of a crow. Could the crow be the key to the solution?
