London, 2020.
Milo Wilson has never been an adventurer. When he goes to London with his friends Ella, Theo, and Ophelia, he expects a few days of casual touristing and fun. But a visit to the Royal Collection Trust museum changes everything. When Milo comes across an old diary, he is so enchanted that he cannot help but steal it. Later on, the diary takes revenge on him by taking Milo and his friends on a journey through time - to a place of betrayal and war, and to a family in great danger.
St. Petersburg, 1917.
Europe is in ruins as a result of the great war. A revolution has brought down the monarchy and the imperial family have been placed in house arrest; praying for a miracle. When one of the grand duchesses stumbles upon an odd-looking man in the palace, she hopes that freedom has finally come. Neither of them could ever suspect that they will have a role in an upcoming drama that Russia will never forget.
