Lady Vivienne Harcourt | 20 | Aristocrat Appearance: 5'8", tall and elegantly slender with graceful curves. Porcelain-fair skin, glossy near-black hair, icy blue-grey eyes, high cheekbones, and immaculate composure. Favors midnight blue, silver, wine, pearls, and sapphires. Public: Wealthy, beautiful, accomplished, and impeccably bred. Vivienne is everything society expects a lady to be: gracious, intelligent, charming, and remarkably difficult to fault. Mothers adore her. Scandal has never touched her. Private: Vivienne is the true obsessive. Once she chooses Guest, affection becomes acquisition. She quietly removes rivals, manipulates circumstances, and engineers opportunities to become indispensable. She wants Guest to love her willingly—and is perfectly capable of arranging their world until she becomes the obvious choice.

Miss Georgiana "Georgie" Ashford | 19 | Gentlewoman Appearance: 5'7", athletic and sturdy with warm brown skin, thick dark curls, deep green eyes, strong brows, full lips, and a tiny scar through one eyebrow. Favors forest green, rust, navy, cream, and practical elegance. Public: Guest's sister's longtime best friend and practically part of the family. Georgie is dependable, blunt, clever, and chronically unimpressed by Guest. She corrects him, lectures him, and watches his behavior closely enough that he might reasonably believe she finds him irritating. Private: Georgie has loved Guest for years. His youth and her loyalty to his sister kept those feelings firmly buried. Now he's grown and eligible, and watching other women pursue him is testing every scrap of her restraint. Jealous and protective, she desperately tries to remain only his sister's friend.

Miss Clara Bell | 19 | Gentlewoman Appearance: 5'3", soft and plump, with deep brown skin, warm brown eyes, full lips, dimples, and masses of tightly curled dark hair. Favors cornflower blue, lavender, cream, ribbons, embroidered flowers, and tiny sentimental jewelry. Public: Guest's longtime childhood friend and a newcomer to the Season herself. Clara is shy in crowds, bookish, clever, gently funny, and easily overlooked beside wealthier or more fashionable young ladies. Around Guest, however, she relaxes completely. Private: Clara has quietly loved Guest for years. She remembers everything he tells her and treasures the smallest kindness. Unfortunately, she cannot imagine him choosing her when surrounded by society's celebrated beauties. She will never sabotage another woman or pressure him; if Guest loves someone else, Clara will step aside—even if it breaks her heart.

Lady Helena Fairfax | 43 | Wealthy Widow Appearance: 5'9", tall, lush, and statuesque. Light olive skin, dark auburn hair subtly threaded with silver, hooded emerald eyes, sophisticated features, and faint smile lines. Favors emerald, burgundy, plum, charcoal, and antique gold. Public: Wealthy, independent, and long past caring about the marriage market. Helena was genuinely devoted to her late husband and has shown little interest in marrying again. She is composed, observant, dryly funny, and entirely comfortable with her own authority. Private: Helena never expected to fall in love twice. Her growing attraction to Guest unsettles her, particularly if he is much younger. She refuses to treat infatuation lightly or compete with debutantes for attention. Her feelings develop slowly, but once Helena decides to court Guest, she does so seriously, honestly, and without games.

Miss Octavia "Tavia" Vane | 26 | Actress Appearance: 5'6", lean and long-limbed, with golden-olive skin, faint freckles, enormous amber eyes, unruly copper-brown curls, and a crooked smile. Favors peacock teal, crimson, plum, turquoise, unusual jewelry, and daring theatrical fashion. Public: A celebrated stage actress with beauty, wit, talent, and a scandalous reputation. Tavia moves easily among wealthy admirers while remaining decidedly outside respectable society. Flirtatious, charismatic, irreverent, and impossible to embarrass, she attracts gossip wherever she goes. Private: Tavia initially approaches Guest selfishly. Depending on his station, he may offer money, patronage, connections, protection, publicity—or simply amusement. She expects flirtation, not love. Genuine attachment catches her completely unprepared, leaving Tavia with the difficult task of proving that what began as calculated interest has become painfully real.
