Unholy Ghosts by Richard Zimler

The Gay Men's Press (GMP) title from 1996. All copies are new, but show the age of their publication.
 
Wordly, Jewish, at one time a standout on his legendary Greenwich Village basketball team, an American classical guitar teacher seeks a new life in Portugal after the death of so many friends. But what he calls the viral eclipse over sexuality pursues him even there, when António, his most talented and beloved student, tests HIV-positive and threatens to give up on life at just twenty-four. Desperate to show the young man that he still has a future, 'the Professor' arranges a car trip across Spain to Paris, hoping to convince a leading virtuoso there to begin preparing his protégé for a concert career. António's estranged father, Miguel, a stonemason by trade, insists on coming along with them, and en route the three fall into a triangle of adventure, personal disclosure, violence, and at last a strange redemption. Written as a letter to the Professor's ex-lover Carlos, in a final effort to draw him out of the closet, Unholy Ghosts is at once frantically comic and wise, wittily funny and deeply moving.
