Arthur Penhaligon's first day at the new school was Monday, and it turned out to be, frankly, hectic: Arthur had to become the owner of the first of the seven Keys to the Kingdom, get into the mysterious House and fight Mr. Monday. It would seem that it’s time to take a little break from adventures... But behind the treacherous Monday comes Gloomy Tuesday, and he has his own plans for our world. This means that Arthur will again have to face serious danger. Garth Nix’s books have long been appreciated by young fans of mysterious stories. However, adults also read them with pleasure. And it’s not surprising, because the fantasy worlds of Nyx are always unique, and the adventures that befall the heroes are always unexpected. “Gloomy Tuesday” is the second book in the “Keys to the Kingdom” series.
