The Recommended Reading Order
For the best reading experience, we recommend following the publication order of the Crown’s Spies series. While each book centers on a different couple and tells a complete, standalone story, the characters belong to the same close-knit circle of noblemen and espionage agents. Reading them in order allows you to see their friendships develop and enjoy recurring appearances from previous heroes and heroines without encountering minor spoilers.
- The Lion's Lady (1988) – Follows Christina Bennett and Lyon, the Marquess of Lyonwood.
- Guardian Angel (1990) – Follows Jade and Caine, the Marquess of Cainewood.
- The Gift (1991) – Follows Sara Winchester and Nathan, the Marquess of St. James.
- Castles (1993) – Follows Princess Alesandra and Colin Hallbrook.
Publication Order vs. Chronological Order
Good news for readers who hate jumping back and forth in timeline order: the publication order of the Crown’s Spies series aligns perfectly with its chronological timeline. The stories unfold sequentially between 1815 and 1819 in Regency England:
- The Lion's Lady is set in 1815.
- Guardian Angel is set in 1815/1816.
- The Gift is set in 1816.
- Castles is set in 1819.
Since the timeline moves straight forward, starting with The Lion's Lady and finishing with Castles is the most natural and rewarding path.
Character Connections and Series World
The core charm of this quartet lies in how the characters are linked. Caine and Colin are brothers, meaning Colin's romance in Castles directly builds on his introduction as a secondary character in Guardian Angel. Additionally, Lyon, Caine, and Nathan are close friends and allies who frequently pop up in each other's books to offer advice, banter, or backup, making the series feel like a cozy, interconnected universe.
Spin-offs and Related Julie Garwood Series
While Julie Garwood is famous for her medieval Scottish romance series, such as the Highlands' Lairds trilogy (beginning with The Secret), there is no official crossover or narrative connection between her Scottish historicals and the Regency-based Crown's Spies. They are completely separate universes, though they share Garwood's signature blend of humorous banter, protective alpha heroes, and spirited heroines.
