Diana Knightley Books in Order

Where to Start: The Kaitlyn and the Highlander Saga

If you are new to Diana Knightley's romance universe, the single best place to begin is with the book that started it all: Kaitlyn and the Highlander (2018). This book introduces Kaitlyn Sheffield, a modern woman who finds herself swept back in time to the windswept Highlands of 18th-century Scotland, and Magnus, the rugged warrior who captures her heart. Because the main series is deeply character-driven and follows the linear emotional growth of Kaitlyn and Magnus as they navigate historical dangers and time-jumping anomalies, jumping in mid-series is not recommended. Start at the beginning to appreciate the chemistry and world-building from day one.

Note on Recent Releases: The series has continued to expand beyond the main 19-book run. Notable continuations include the Time is a Wheel: The Wolf King Trilogy, which contains Long Live the King, The Dawn, and the March 2025 release The Empire and the Wolf King. While these later books are technically part of the main continuity, the author has designed the trilogy so that it can also function as a standalone entry point for new readers.

The Rules of Time Travel Trilogy

Set in the same expansive universe as the main series, The Rules of Time Travel (officially titled The Scottish Duke and the Rules of Time Travel) is a trilogy that shares the same magical mechanics and lore. It consists of:

While this trilogy features a different set of primary characters, it is set in the same shared world. You can read this trilogy completely independently of the main Kaitlyn and Magnus books, but reading it after the first few books of the main series will give you a richer understanding of how time travel operates in Knightley's books.

The Campbell Sons: Contemporary Spin-off

For readers who want a break from historical settings and time-travel paradoxes, Knightley offers The Campbell Sons series. This contemporary Scottish romance series focuses on modern relationships, family ties, and rock-star glamour. The reading order is straightforward:

1. Karrie and the Rock Star (2022)
2. Blakely and Liam (2022)

Although these books are contemporary and do not feature active time travel, they exist in the same literary universe as the historical series. Characters from the broader Knightley universe make brief crossover appearances, making it a treat for long-time fans, though it is fully readable as a standalone contemporary romance duology.

Luna's Story: An Apocalyptic Departure

If you enjoy Knightley's emotional depth but want a completely different setting, Luna's Story is a post-apocalyptic romance trilogy. This series is separate from the time-travel continuity and should be read in order:

1. Leveling (2018)
2. Under (2018)
3. Deep (2018)

This series follows the characters Luna and Beckett as they fight for survival and love in a flooded world reshaped by catastrophic storms. It features Knightley’s signature emotional intensity and strong-willed heroines but is set in an entirely distinct, non-historical universe.

Standalone Works

For a quick, self-contained story that doesn't require a multi-book commitment, Knightley published Artair the Bold in 2024. This standalone novel is set in the same historical Scottish realm and is perfect for readers who want a taste of her historical style before committing to the main 19+ book Kaitlyn saga.

Practical Reading Advice and Caveats

When diving into Diana Knightley's bibliography, keep these structural tips in mind:

• Commit to the Chronology: Do not skip books in the main Kaitlyn and the Highlander run. Because the relationship and family history build linearly, skipping entries will lead to confusion about character relationships and the overall timeline.
• Flexibility with Spin-offs: You can pause the main series at any time to read The Rules of Time Travel or The Campbell Sons without ruining the main plotline.
• Pen Name Clarification: Note that the author also writes Young Adult fiction under the pen name H.D. Knightley. Those books are distinct from her adult paranormal romance bibliography.
