Fountain of Youth

"Two generations of dementia are enough!" Robert Glickman declares in his quest to die with dignity and the likelihood he will be next. To that end, he uses his grandson's sixth grade quiz book, a locked away metal box, and a secret weapon that eventually comes back to haunt him.
In the meantime, he is embroiled in the lives of other residents: his neurotic sister, Essie who plots to steal his secret weapon for herself; beautiful Christina Abernathy, a retired psychotherapist he instantly falls in love with; Hester, a young server at the Fountain who suffers from progressive mutism; Boyle, a man of mystery with a questionable past for good or evil (Glickman isn't sure which); and Boyle's grandson, Santini, a troubled young man caught between the dope dealers he runs with and the FBI wanting to use him.
Will Glickman and Essie beat dementia? Can he win over Christina? And what about Hester, Boyle, and Boyle's grandson?
