Dear Captain...

"They call me the Anchor because I hold the station together. They don't know I'm actually drowning."

Twelve years. Twelve years of being a shadow in the 118, a mechanical genius who speaks to machines because people are too loud. Eli Mercer is a ghost in a turnout coat, living his life through unsent letters to a dead Captain and the cold comfort of routine. He doesn't need friends, he doesn't need a family, and he certainly doesn't need to be seen.

Then comes Eddie Diaz.

A man who knows all about "dead space" and the weight of a uniform. When a catastrophic rescue leaves Eli buried in more than just rubble, it's Eddie who reaches into the dark to pull him out.

Now, Eli is forced out of the shadows and into the bright, messy world of the Diaz household. Between Lego structural snags with Christopher and quiet porch confessions with Eddie, the walls Eli built are starting to crumble. But as ghosts from Eddie's past resurface, Eli's old instincts scream at him to disappear again.

In a job where everyone is a hero, Eli has to learn the hardest lesson of all: Who anchors the man who holds everyone else up?
