The novel opens with a tennis match between David and Carol, where the rhythm of the ball—'back and forth, back and forth'—mirrors the push-and-pull of their relationship. The game ends with a kiss, but the victory is Carol's, and David's response—'I kiss the fingers that defeated me'—hints at a dynamic where admiration and condescension coexist. This scene sets a pattern: physical activity and outdoor settings recur as stages for emotional negotiation.

Later, a letter from Connie to Carol introduces a contrasting voice—breezy, self-aware, and financially anxious. Connie describes winning over Andy's mother with a 're-debut' and worries about proposing marriage. The letter's frankness about money ('a man can hide a hundred faults in one fold of a pocketbook') and its playful self-deprecation ('I am an orphan, and a widow, and a stranger') suggest that the novel will balance romantic idealism with practical concerns.

Tennis, Letters, and the Rhythm of Courtship

The opening chapter uses the tennis match as a microcosm of courtship: competitive, physical, and governed by unspoken rules. The players' movements are described in precise, repetitive language—'back and forth, back and forth'—creating a hypnotic rhythm that breaks only when Carol wins and they kiss. David's gesture of kissing her fingers acknowledges her skill but also frames it as charming rather than threatening. This tension between equality and condescension reappears in Connie's letter, where she describes her future mother-in-law as 'adorable' and 'pink and gray, with dimples,' yet immediately undercuts the warmth by noting the man's wealth. The letter form allows Connie to voice doubts—'I wonder—I wonder'—that she cannot express directly. Together, the tennis match and the letter establish a pattern: the novel uses physical action and epistolary confession to explore how women navigate love, ambition, and social expectation.

Illness and the Landscape of Recovery

In Chapter XV, the setting shifts to a New Mexico sanatorium, where Carol and David sit on canvas chairs 'wrapped in rugs' despite summer, watching 'the shadows of evening tarnish the gold of the mesa.' The landscape is both beautiful and harsh—the cold evenings, the sand-storms, the 'dark valley' of illness that each character believes they have hidden from the other. David's improving health is measured by his temperature dropping 'below ninety-nine' and his 'ravenous' appetite, but the narrative undercuts this optimism: the doctors 'might be wrong,' and the couple's planning for their daughter Julia's future feels like a fragile defense against uncertainty. The passage reveals a pattern of mutual protection—each spouse conceals the severity of the illness—and a reliance on the natural world as a backdrop for emotional truth. The mesa, with its 'gold' tarnished by shadow, becomes a symbol for the precariousness of hope.

Sisters, Ambition, and the Weight of Expectation

Connie's letter to Carol is a study in self-presentation. She describes her 're-debut'—a term she coins—as a performance that wins over Andy's mother, yet she immediately questions the relationship: 'I can't tell him until he asks me, can I?' The letter oscillates between bravado and vulnerability, between delight in the mother-in-law's dimples and suspicion of the family's wealth. Connie's ambition to write 'magnificent stories' is mentioned almost as an aside, sandwiched between descriptions of sleeping in the mother's nightgown and using her toilet articles. This juxtaposition suggests that creative ambition must compete with domestic and romantic plots. Carol, meanwhile, is the recipient of this confidence, positioned as the stable sister who has already married and had a child. The novel thus uses the sisters' correspondence to explore different paths for women: Carol's role as minister's wife and mother, and Connie's struggle to reconcile love, money, and artistic aspiration.

Readers will find that Hueston's novel rewards attention to its structural symmetries: the tennis match that opens the book finds echoes in later scenes of physical exertion and emotional contest. The letters, too, are not mere filler but a deliberate counterpoint to the third-person narrative, allowing characters to speak in their own registers. Pay particular attention to how the landscape—whether a tennis court, a mesa, or a Chicago hotel—shapes the characters' ability to speak honestly. The novel's title, Sunny Slopes, may promise ease, but the text itself is more interested in the shadows that fall across those slopes.
