My Uncle's New Eyes

When Michael Reeves gets suspended from the rural Arizona boarding school/rehab facility where his rich stepfather put him, Mike's mom, at her wit's end, sends him to live with a family member who has a hacienda in the countryside. Enter Uncle Jimmy.
Michael's great-uncle Jimmy "Grim Reaper" Reeves is a former world champion boxer who is punch-drunk from a hard career, on top of suffering the usual vagaries of old age. He's also the subject of an experiment, a revolutionary new therapy that holds the promise of helping Uncle Jimmy recover his memories and potentially altering the lives of millions of other seniors, if successful.
It sounds good, only what if the ex-boxer remembers some things that were perhaps best left forgotten?
My Uncle's New Eyes is part coming-of-age novel, part science fiction meditation, with more than a dash of noir and horror thrown in.
