Catherine Doyle Books in Order

Where to Start with Catherine Doyle

Catherine Doyle is a master of blending high-stakes drama, rich folklore, and emotional depth. Because her catalog spans different age groups and genres, the best place to start depends entirely on what you like to read:

• For Romantasy Fans (YA): Start with Twin Crowns (co-authored with Katherine Webber). It is a high-spirited, magical royal-twin-swap story packed with humor, romance, and political intrigue.
• For Darker Fantasy & Assassin Lore (YA): Start with The Dagger and the Flame, the opening book of her City of Fantome trilogy. It features a lush, gothic setting with thieves, assassins, and a slow-burn romance.
• For Magical Middle-Grade Readers (and kids at heart): Start with The Storm Keeper’s Island. Set on a fictionalized version of Arranmore Island where her own ancestors lived, it is a deeply moving tale of family, ancestral magic, and memory loss.
• For Gritty YA Romance & Suspense: Start with Vendetta, the first book in her Blood for Blood trilogy, which reads like a modern-day teen mafia retelling of Romeo and Juliet.

The Twin Crowns Universe Reading Order

Co-authored with Katherine Webber, the Twin Crowns series is a blockbuster YA romantasy about long-lost twin princesses—one raised to be a proper royal, the other raised in secret by witches—who swap places to save their kingdom.

2. Cursed Crowns (2023) – The twins must navigate the fallout of their swap, deal with hostile kingdoms, and keep their crowns.
3. Burning Crowns (2024) – The thrilling conclusion of the sisters' fight to unite their kingdom and defeat ancient evil.

The Companion and Spin-Off Novels:

• Captain of Fates (2025) – A spin-off novel written solo by Katherine Webber, focusing on the sky-sailing pirate Captain Marino Pegasi.
• King of Beasts (2026) – A standalone spin-off novel written solo by Catherine Doyle, centering on King Alarik Felsing.
