Borderlines of the Heart is a sweeping, emotionally charged love story that traces the jagged edges of identity, migration, and belonging across the U.S.-Mexico border and deep into the heart of the Latinx experience.

When Marisela, a young Salvadoran woman fleeing violence and economic despair, boards a rickety night bus in Chiapas, she doesn't expect to find connection—let alone the quiet spark of something deeper. But beside her sits Julián, a Mexican-American chef returning from visiting family. He's confident, charming, and safe in ways she has never known. Their bond is tentative but immediate. Yet before their journey even begins, it's torn apart by an immigration raid. Marisela is detained. Julián watches helplessly. Two lives, traveling the same road, suddenly diverge.

Weeks later, in the pulsing immigrant neighborhoods of Los Angeles, fate reunites them at a community event in Boyle Heights. Their chemistry resurfaces, but so do the fractures—cultural, linguistic, and personal. Marisela speaks in "vos," guards her trauma tightly, and works tirelessly to support her family back home. Julián, fluent in "tú" and privilege, has dual residency and a growing culinary career, but struggles to connect with a past he's only inherited, not endured. As they fall in love, so too do they clash—over pupusas vs. tacos, language, family, and pride. Their intimacy is sweet but unsteady, tested by casual racism, cultural stereotypes, and deep internal wounds.

Told in eighteen lyrical, character-driven chapters—each rooted in Latinx traditions, environments, and tensions—Borderlines of the Heart interweaves the richness of Hispanic food, language, and resilience with the harsh realities of gangs, child support battles, deportation, drug abuse, and generational poverty. From late-night Boyle Heights street parties and kitchen arguments to protest marches, poetry readings, and wedding dances, this novel paints a full, tender, and sometimes painful portrait of modern Latinx life.

As Marisela finds her voice and Julián learns to listen, their love transforms from infatuation into something radical—solidarity. Together, they build "Corazón Cruzado," a food truck serving fusion and heritage in equal measure. But true healing only comes when they journey back to El Salvador, to walk barefoot on the beach where Marisela once prayed for escape. There, under open skies, they finally understand: borders may never vanish—but bridges can be built.
