In Sincerely Yours, Sonia D. Hebdon drops readers into Haven Cove in 1989, where Josie, a sharp, music-soaked teenager with a gift for language, falls into a charged romance with her new neighbor Blaine while secretly writing an advice column called “Sincerely Yours.” What begins as an 80s-inflected love story of mixtapes, eyeliner, and illicit nights out steadily opens into something stranger: a paranormal narrative about writing itself, about stories that breathe, unfinished worlds, and the frightening possibility that words do not merely describe reality but conjure it. The novel openly frames itself as a paranormal love story rooted in 1980s music and in the idea that certain writers can create literal worlds, and that premise becomes the book’s true engine.

What I liked most was the book’s unabashed sincerity. Hebdon is not aiming for cool detachment; she wants feeling, and she goes after it in full view. Josie and Blaine are drawn with the kind of heightened, romantic glow that suits the novel’s cassette-tape heart, and the pages are thick with Cure songs, club lights, handwritten letters, and the intoxicating self-invention of adolescence. I found that atmosphere persuasive even when the prose grew ornate, because the book’s emotional weather is so clear: loneliness, awakening, first love, artistic hunger, the longing to be seen as oneself rather than as a role assigned by family or town. The advice-column scenes also give Josie a moral and emotional gravity that keeps her from becoming just another dreamy heroine; her anonymity becomes its own form of courage.

My reaction to the novel’s second half was more mixed, but still engaged. Once the Whitlock Society and the metaphysics of authorship move closer to center stage, the book shifts from nostalgic romance into meta-paranormal fantasy, and that turn is genuinely intriguing. I admired the ambition of a story that asks what happens to unfinished narratives and imagines rare writers as conduits who generate actual worlds. The book feels stuffed with mood, mythos, sentiment, and soundtrack, but that excess is also part of its personality. I never had the sense of a cynical machine at work; I felt the presence of a writer who loves 80s music, believes in the numinous charge of words, and is willing to let teenage feeling burn bright instead of sanding it down into irony.

I’d recommend Sincerely Yours to young adult readers, especially those who enjoy YA paranormal romance, clean fiction, coming-of-age fantasy, and music-laced stories with a gothic shimmer. Readers who love emotionally direct fiction and retro atmosphere will probably be its natural home crowd. In spirit, it sits somewhere between the swooning supernatural pull of Twilight and the mixtape melancholy of an 80s-mad Sarah Dessen alternate universe, though Hebdon’s metafictional streak gives it its own curious voltage. My verdict: this is a heartfelt, melodramatic, odd little spell of a book, and when it works, it reminds me that sincerity is not a weakness but a strength.
