Five children of graveyard shift workers-Miles, Esperanza, Kwame, Jin, and Aaliyah-discovered the Graveyard Shift Academy, an underground school hidden beneath an abandoned shipping yard in Oakland. Built generations ago by night-shift workers, the Academy trained each child in the trade of their parent: mechanics, nursing, transit, logistics, and crane operations. After passing a final test that proved they could only succeed together, the five graduated and began carrying the Academy's knowledge into the world above. As the first book ended, the bell began warming up for a new class.

This is Miles's story.

The wrench Miles received at graduation was not an ordinary tool.

He discovered this on the first morning after the ceremony, when he woke up and found the wrench on his nightstand, warm to the touch, humming with a frequency so low it was more feeling than sound. He picked it up and felt it-the same way he felt engines, the same way his hands read vibration and translated it into meaning. But the wrench wasn't vibrating with its own energy. It was vibrating with memory.

He saw flashes. A man's hand gripping the wrench in a shipyard, turning a bolt on a steam engine in what looked like 1920. A woman's hand using it to adjust a diesel injector in what might have been the 1950s. A teenager's hand-darker than the first, lighter than the second-using it to tighten the mounting bolts on a container crane in the 1980s. Hands across decades, holding the same tool, fixing the same essential things, keeping the same machines alive.

The wrench remembered every mechanic who had ever held it. And now it was his.

Miles sat on the edge of his bed, holding the wrench, listening to its memories, and he understood that his education at the Graveyard Shift Academy was not over. It had barely begun. Book One was the introduction. The discovery. The first spark.

Book Two was the engine room. The real one. The one that went deeper than the workshop he'd trained in. The one that held secrets the Academy had not yet revealed.

The wrench pulsed in his hand, warm as a heartbeat, patient as iron.

Miles got dressed, put the wrench in his back pocket, and went to school. He had a feeling he wouldn't be there long.
