The last days of December. The last days of our lives.
Twenty-six-year-old Hari Blackwood is among the last humans.
Windsor Castle is a sanctuary from the Ferals, the planet's dominant species...
But Hari must not ask questions...
Don't ask why people are disappearing.
Don't ask why Henry VIII's ghost haunts him.
Don’t ask why a Feral wants his help.
Don't ask why a suicidal young woman may have the answers.
... And never ask why the castle is safe from attack.
