Harper St. George Books in Order: The Complete Reading Guide

St. George's historicals sit slightly later than classic Regency — the 1870s and beyond, when railroad and steel money sent a generation of American heiresses across the Atlantic to rescue cash-poor aristocrats. It is the perfect engine for romance: marriages of convenience, fish-out-of-water heroines, and heroes whose pride costs more than their estates. Both of her series share this world, and one flows into the other, so the reading order below is also the recommended order.

The Gilded Age Heiresses series in order

The series that made her a book-club staple: the Crenshaw family's iron fortune meets the British aristocracy, one sibling at a time.

1. The Heiress Gets a Duke (2021) — August Crenshaw is the practical sister, happy at the family firm, until the Duke of Rothschild comes courting her younger sister — and decides, inconveniently, that he wants August instead. An arranged-marriage bargain with real teeth, and one of the best "I am not a prize to be sold" heroines in the genre.
2. The Devil and the Heiress (2021) — Violet Crenshaw flees an engagement she never agreed to, climbing into a carriage with Christian, Earl of Leigh — a rogue with his own reasons for helping her run. A runaway-heiress road romance with a scheming hero who gets thoroughly humbled.
3. The Lady Tempts an Heir (2022) — Maxwell Crenshaw, the brother, and Lady Helena March, a widow devoted to her causes, agree to a fake engagement to keep their meddling families at bay. Fake courtship, genuine longing, transatlantic complications.
4. The Duchess Takes a Husband (2023) — Camille, the American duchess whose cold marriage haunted the earlier books, is widowed and free — and Jacob Thorne, an ambitious club owner, needs a respectable fiancée. Her counteroffer is bolder than his. A tender, quietly radical finale about a woman reclaiming herself.

The Doves of New York series in order

The follow-up series, set in the same world: the Dove sisters were raised on the wrong side of their wealthy father's respectability, and each book follows one of them claiming a future — and a love — on her own terms.

1. The Stranger I Wed (2024) — Cora Dove needs a husband to unlock her inheritance; Leo, the pragmatic Earl of Devonworth, needs money for his political ambitions. A clear-eyed marriage of convenience that neither party manages to keep businesslike.
2. Eliza and the Duke (2025) — Eliza Dove's story pairs the gentlest sister with a decidedly ungentle hero from the London streets whose fortunes change dramatically. Second-chance yearning across a class divide.
3. The Dove and the Rogue (2026) — the latest entry, giving the remaining Dove sister her turn at scandal and happiness.

Where to start with Harper St. George

Start with The Heiress Gets a Duke. It is the strongest single entry point, it sets up the world's rules — dollars for dukedoms, love strictly off the ledger — and the three books that follow reward you for knowing the Crenshaws. Then move straight into The Stranger I Wed; the Doves of New York stands on its own feet, but it is set after the Heiresses books and shares their world, so reading it second is the natural path. If you must cherry-pick one book, make it The Heiress Gets a Duke or The Stranger I Wed — both are marriage-bargain romances that showcase exactly what St. George does best: heroines with leverage, heroes with debts, and negotiations that melt into devotion.
