A Cryptic Telegram. A Deadly Secret. A Race Across Russia.

When a mysterious telegram signed with the initials NRR arrives, fourteen-year-old Amy Cahill and her brother Dan are pulled into a dangerous hunt across Russia — one that promises answers about a Nazi-stolen treasure and the fate of the Russian royal family.

But as the clues lead deeper into enemy territory, Amy and Dan begin to suspect they've walked straight into a Lucian trap. And the real prize? The truth about their parents' deaths — a secret someone will kill to keep hidden.
