Letter 44 is widely considered one of Charles Soule’s best creator-owned works. The series opens on Inauguration Day, when the new president learns that aliens are building something in the asteroid belt and that his predecessor launched a secret mission to investigate.
The story runs across six collected volumes, alternating between the White House political thriller and the space mission. It explores questions about government secrecy, leadership under impossible circumstances, and first contact.
