The Ruby Vaughn Series in Order

About the Ruby Vaughn series

Series Premise

Ruby Vaughn, a disgraced American heiress who fled scandal in New York to build a new life in Exeter, England, works at a rare bookstore alongside her elderly employer and housemate, Mr. Owen, after the Great War. When she is drawn into dangerous mysteries—often involving cursed estates, grimoires, séances, mediums, or supernatural-tinged crimes—she uses her sharp wit, resilience, and bookish knowledge to investigate, uncovering dark secrets while confronting her own traumatic past and the era's lingering shadows of war and loss.

The series should be read in order, as it follows Ruby's continuous personal journey, evolving relationships (including with recurring allies and a slow-burn romantic interest), deepening character growth, and subtle connections across cases involving occult elements and her own history—while each mystery offers a self-contained investigation and resolution, reading sequentially enhances emotional depth, avoids spoilers on Ruby's backstory and key developments, and captures the building gothic atmosphere and recurring themes.

Main Characters

Ruby Vaughn: The spirited protagonist, an unconventional American heiress exiled from New York society; bold, pleasure-seeking yet deeply scarred by war service as an ambulance driver, family loss, and scandal, she is intelligent, contrarian, insightful, and caring—using her contrarian streak as protection while growing through mysteries into a more open-hearted investigator.

- Mr. Owen: Ruby's octogenarian employer, housemate, and mentor at the rare bookstore; bookish, wise, and quietly supportive, he often accompanies her on adventures, providing historical knowledge, emotional grounding, and occasional comic relief through his eccentricities.

- Ruan Kivell: A Cornish folk healer and Pellar (witch/healer figure); enigmatic, self-described witch with deep ties to local folklore, he becomes Ruby's recurring ally and slow-burn romantic interest, bringing supernatural insight, protective instincts, and a grounded counterpoint to her rationality.

Setting

The series is set in interwar Britain, primarily in Exeter and surrounding regions, with stories venturing into remote Cornish countryside estates like Penryth Hall, Scottish Borders castles such as Manhurst, Oxford's academic halls, and other atmospheric British locales. Environments feature crumbling gothic manors with ancient curses, fog-shrouded villages, rare bookshops filled with grimoires and occult texts, séance rooms, folk healer cottages, and the lingering post-Great War atmosphere of grief, hedonism, and social change. This vivid backdrop contrasts elegant yet decaying grandeur with rural superstition, creating a richly gothic stage where history, folklore, and modern skepticism collide.

Tone & Themes

Gothic, atmospheric, and engaging with a blend of suspenseful tension, wry humor, and emotional poignancy, the tone evokes classic historical mysteries with vivid period details, immersive settings, and a modern sensibility in its heroine. It balances eerie supernatural hints and gothic dread with grounded character moments, light romantic sparks, and satisfying reveals without excessive horror. Themes explore trauma and resilience after war and personal scandal, the clash between rationality and the inexplicable, redemption and second chances, the power of knowledge (especially rare books and folklore), women's independence in a restrictive era, forgiveness amid betrayal or loss, and the idea that some curses—literal or figurative—are rooted in human actions rather than fate.

The Ruby Vaughn series enchants with its lush gothic atmosphere, sharp-witted heroine, and mysteries that weave folklore, history, and human darkness into compelling tales of resilience and revelation. Jess Armstrong crafts an addictive blend of post-war intrigue, subtle supernatural chills, and heartfelt growth that lingers like mist over Cornish moors—leaving readers spellbound, rooting for Ruby's next adventure, and savoring the quiet thrill of uncovering truths in a world still haunted by war and wonder.
