Gregory Wallace 
The Invisible Clock [EPUB ebook] 
A Legacy in Gears

He built a life around the whirring precision of biomechanical gears, crafting prosthetic limbs that mirrored the intricate dance of human potential. Now, retired engineer Gregory Wallace faces a different kind of clock – the silent, insidious ticking of obsolescence.  Society whispers that his time is over, but Gregory refuses to fade away. He finds a new rhythm in the vibrant chaos of the Jefferson Street Community Center, a haven in Chicago’s rapidly gentrifying Lower West Side, and in the raw talent of the teenagers who call it home.
Kayla, fiercely protective of her brother who uses a wheelchair, dreams of mobility beyond limitations.  Brian, a brilliant coder haunted by past failures, yearns to reignite his creative spark. Todd, a budding entrepreneur, grapples with balancing ambition and responsibility to his ailing grandmother.  In their anxieties and uncertainties, Gregory sees reflections of his younger self, and a chance to rewrite his own legacy.
He challenges them to build assistive devices, merging cutting-edge biomechanics with the lived experience of disability and need.  Their project, ‘Project Phoenix, ‘ takes flight, transforming the community center into a hive of innovation.  But progress isn’t without its obstacles. The center’s ambitious young director, obsessed with “modernization, ” sees Gregory’s methods as archaic.  A prestigious national engineering competition offers an unprecedented opportunity, but also a daunting ethical dilemma, forcing the students to choose between corporate allure and community needs.  And looming over them all is the shadow of a developer, threatening to demolish the center and erase the very community they’re fighting to empower.
As the lines between innovation and exploitation blur, Gregory and his students must confront a stark choice: compromise their ideals or risk everything to protect the heart of their community. The competition becomes a battle not for a trophy, but for the soul of the Lower West Side.  In the face of relentless pressure, they discover not just their technical prowess, but the enduring power of human connection, proving that true progress is built not on discarding the old, but on embracing the wisdom of experience and the vibrant energy of the new.
