Amazon is taking preorders of Justin Richards’ Doctor Who: The Time Lord Letters Kindle eBook for FREE ($29.99 value) for a limited time. It’s scheduled for release September 29, 2015.

No one could travel through time—past, present, and future—as much as the Doctor does without leaving an impression. Much of what we know about this mysterious figure comes from the planets he saves and the monsters he defeats. But we’ve had little knowledge of his writings until now.

The Time Lord Letters is a collection of more than one hundred letters, notes, and jottings both by and to the Doctor—correspondence by turns entertaining and inspiring, funny and flippant, brilliant and incredible.

From the Doctor’s plea to the Time Lords to help end the War Games to an extract from the written defense he submitted at his subsequent trial; from his application for the post of Caretaker at Coal Hill School to his apology to the Queen for missing dinner; from telepathic messages to the High Council on Gallifrey to his famous letter to Santa Claus—The Time Lord Letters captures the best and most dramatic moments of an impossible life.
