Darkness is ready to engulf Annun - an amazing world born from dreams and dreams; it, like a mirror, reflects the dream of London as seventeen-year-old Fern wants to see it. She and her twin brother Ollie belong to a mystical ancient order of knights who guard dreamers in Annun: if a dreamer dies in the other world, then he is no longer destined to wake up in reality. Fern spends every night in Annun, but it is becoming increasingly difficult for her to fulfill her destiny, because her magical power has passed on to her brother. So their relationship, already darkened by a cruel past, becomes even more strained... Meanwhile, the twins' sworn enemy, the sorcerer Midraut, who seeks to destroy Annun, anticipates victory. To confront him, you must return King Arthur's missing sword - Excalibur - and find the mysterious Grail. Can Fern save the world she loves so much and see hope, light and wonder return to Annwn? The final book in the Midnight Twins trilogy - for the first time in Russian!
