What is the order of Lucinda Riley’s books?

The Seven Sisters series in publication order

Eight books, one pattern: an interlocking puzzle that must be read in sequence to appreciate the hidden anagrams and character arcs. The series begins with The Seven Sisters (2014) and concludes with Atlas: The Story of Pa Salt (2023), co‑written with her son Harry Whittaker (Pan Macmillan (publisher of the series)).

# Title Publication Year
1 The Seven Sisters 2014
2 The Storm Sister 2015
3 The Shadow Sister 2016
4 The Pearl Sister 2017
5 The Moon Sister 2018
6 The Sun Sister 2019
7 The Missing Sister 2021
8 Atlas: The Story of Pa Salt 2023

The implication: jumping into any later book spoils the gradual unmasking of Pa Salt. Readers who start at the beginning report a far richer experience.

Standalone novels chronology

Ten novels outside the Seven Sisters universe, each independent and readable in any order. The first was The Orchid House (also known as Hothouse Flower) in 2010 (OrderOfBooks (bibliography tracker)).

  • The Orchid House (2010) – also released as Hothouse Flower
  • The Girl on the Cliff (2011)
  • The Light Behind the Window (2012)
  • The Midnight Rose (2013)
  • The Olive Tree (2016) – also titled Helena’s Secret
  • The Love Letter (2018)
  • The Butterfly Room (2019)
  • The Hidden Girl (2022) – posthumous release
  • The Last Love Song (2023) – posthumous release

The pattern: Riley’s standalone works explore similar themes of family secrets and dual timelines, but they don’t require a specific order.

What is the latest Lucinda Riley book?

Posthumous releases and future titles

The most recent published novel is The Last Love Song (2023), released after Riley’s death (Pan Macmillan (publisher of the series)). Before that came The Hidden Girl (2022). As of early 2025, no new titles have been announced for 2026; any future works will be completed by her son Harry Whittaker (Lucinda Riley official site (author’s estate update)).

The catch

The posthumous novels were edited from Riley’s manuscripts, so they remain authentic to her voice – but the series finale, Atlas: The Story of Pa Salt, was co‑written with Harry Whittaker, giving it a slightly different feel.

Which Lucinda Riley book is considered her best?

Reader favorites and critical acclaim

Across reader platforms, The Seven Sisters consistently ranks as the highest‑rated book in her bibliography (Goodreads (reader ratings platform)). Fans also heap praise on The Storm Sister and The Sun Sister for their gripping plots and rich historical settings. Critics highlight Riley’s skill at blending historical fiction with family sagas, a formula that made the series a global phenomenon (Pan Macmillan (publisher of the series)).

“Many readers agree that The Seven Sisters is the strongest entry in the series – it sets up the mystery of Pa Salt in a way that hooks you instantly.”

– Goodreads top reviewer (common reader sentiment)

For most readers, the series opener doubles as Riley’s magnum opus, but the deeper puzzle of Pa Salt means that no single book delivers the full payoff.

Do you need to read Lucinda Riley books in order?

Series vs. standalone reading approach

The Seven Sisters series should be read in publication order to follow the chronology and character arcs – especially the overarching mystery of Pa Salt (Pan Macmillan (publisher of the series)). Standalone novels are independent and can be enjoyed in any sequence. The recommendation: start with The Seven Sisters to build the emotional foundation.

Why this matters

Reading the series out of order means losing the layered reveals that make the anagrammatic puzzle work. The series is designed as one continuous story, not a set of interchangeable episodes.

What is PA salt an anagram for?

Unraveling the puzzle in The Seven Sisters

According to the Lucinda Riley official site (series page), “PA salt” is an anagram that reveals a key character’s name in the series. The anagram is part of the “Sisters and Cast” illusions that add depth to the narrative. Solving it enhances the reading experience for fans – but the official site leaves the precise answer for readers to discover.

Why this matters

The anagram “PA salt” is not just a gimmick; it’s the linchpin of the entire series mystery. Readers who decode it before Atlas: The Story of Pa Salt will feel a satisfying click at the finale.
