The Light We Keep (The Dark Blade Trilogy, #1.2)

For centuries, the Festival of Lights has illuminated the Watch Guard Tower.
For generations, tradition has held firm.
Until now.
With their preparations in disarray, Dan must choose between the traditions that shaped him and those he’s been taught to distrust. In the tower’s deepening darkness, he’ll discover that the strongest light often comes from the most unexpected flame.
 “The Light We Keep” is a short holiday story set in the World of Aramatir, occurring between the events in Dark Blade Forged and the next book, Dark Blade Tempered, but most readers will be able to enjoy the story without having read book 1.
