Neon Gods — J.D. Gallagher

Nathan Coldwell is dying. A tumor is erasing his memories one by one, as he battles to remember his own life story, he is forced to remember his childhood friend Layla Toner and the small-town life they led in the Irish countryside where a life or death pact made in the tail end of their childhood years still reverberates years later, shaping the separate paths they have taken and the lives they have chosen to live.
