Undetectable is a story of love, loss, and viral loads, a memoir of long-term survival with HIV. From graduate student in 1989, who contracts the virus from the love of his life, to writer in 2018 visiting the slums of Nairobi, the author finds his own drama intertwined with the astonishing stories of his HIV+ peers, narratives that intersect the path of his travails and act as foils to the foibles of a gay man who comes out, falls in love, and faces a death sentence at the beginning of his career. In the fight for medicine, support, and love, the author learns the power of linking self to other as he faces stigma, heartbreak, and fear with a visceral resilience.
