The air in the garage was thick with the smell of motor oil and sawdust. Michael ran a hand over his chin, a dazed expression on his face. He'd been expecting tools, spare parts, maybe some old car magazines. What he found in his father's toolbox was an altogether different matter. The first entry on the list, written in a bold, unwavering hand: "Build a race car."

Michael's chest tightened. His father, the quiet, reserved engineer, the man who preferred a good book to anything else… wanted to build a *race car*? He slowly closed his eyes, his mind struggling to reconcile the image of his father with the words on the page.

The following entries provided further revelations. “Learn to play guitar.” “Travel to all the continents.” “Kiss a stranger.” Michael felt a jolt run through him, an almost electric sensation. He couldn’t believe this.
