Robert A. Karl’s Night of San Juan is an ambitious young adult novel that weaves first love and identity exploration with heavy socio-political backdrops: colonial tension, family hostility, gang violence, and the devastating impact of Hurricane Maria. Set against 2017 Puerto Rico, the narrative follows Saint John, a U.S. serviceman’s son, and Mateo, a local teen trapped by familial trauma and gang ties, as they navigate a forbidden romance.

In 2017, military brat Saint John relocates from Brooklyn to San Juan, long accustomed to frequent moves and keeping his attraction to boys a secret. Meanwhile, fifteen-year-old Mateo lives in Río Piedras, skipping school to avoid relentless bullying while hiding both his sexuality and his terror of local gang violence. Compounding Mateo's struggles is his family's deep-seated resentment of Americans; a generational grudge passed down through the women in his household following a past assault by a U.S. soldier.

The strength of the novel lies in its atmospheric rich setting and the poignant symbolic resonance of its titular ritual. Karl uses the backdrop of San Juan, from Piñones to secret riverside hideaways, to ground Saint and Mateo’s romance in authentic geography and shared vulnerability. The central romance offers a delicate counterweight to the external chaos, using the Night of San Juan tradition as an emotional anchor that symbolizes hope and endurance.

With multiple events and happenings such as conversion camp threats, intergenerational anti-American trauma, gang murders, and a pair of catastrophic hurricanes into a single narrative, the plot feels overburdened at times. The post-Hurricane Maria separation, stretching across communication blackouts and an abusive relocation to Connecticut, threatens to displace the delicate intimacy built in the first half.

Ultimately, Night of San Juan succeeds as a powerful testament to resilience and young love. While its sprawling plot points occasionally risk overshadowing its emotional core, the story’s authentic atmosphere and triumphant reunion offer LGBTQ+ readers a deeply cathartic and memorable coming-of-age journey.
