- Book 3 has many differences compared to The Crown & The Flame, Book 1 and The Crown & The Flame, Book 2. These are:
- The Nevrakis are no longer the main antagonists of the series.
- Some premium characters recruited in Book 1 namely Severin, The Bear, and the Mechataur don't appear in this book.
- The book cover features a new stylization of the title, as well as shows Kenna and Dom fighting against each other as enemies instead of working together as allies.
- Book 3 only contains one system of points instead of two, the Legend point. It fills up from all playable characters' choices.
- This is the only book where two characters can be recruited simultaneously, either without requiring a plot (Florian and Zenobia), or requiring only one purchase (Hex and Anton). This book also lets you recruit a character immediately before the beginning of the story, King Luther.
- After Chapter 6, all known armies and locations of The Five Kingdoms have been revealed.
- In Chapter 17, the player has the option to marry Kenna to Dom, Raydan, Diavolos, Tevan, Val, Annelyse, or stay single.
- In Chapter 17, if the player recruits and preserves every ally, then there will be 24 characters (excluding Kenna and Dom) at the Stormholt Castle. This includes six from Book 1, seven from Book 2 including Val and eleven from Book 3.
- A pattern occurs in the title of the chapters in this book. The word "The" is at the beginning of every title, ending with another word or phrase.
- Dom's Hawk appears to make cameo in Chapter 13 of The Royal Romance, Book 3 as Tiberius, a wild hawk roaming around Your Character's Duchy.
- In a premium scene with Liam in Chapter 15 of the same book, he mentioned that a legendary warrior united the Five Kingdoms under her rule. He was most likely referring to Kenna Rys.
- This is the third book in the Choices universe to be set in the past. The other three being the first and second book in The Crown & The Flame trilogy; as well as Desire & Decorum.
- In Chapter 6 of America's Most Eligible: Season 10, if Your Character joins Derek and the Handsome Stranger in the hot tub and picks to ask them about their favorite show, they both say The Crown and The Flame.
- Your Character admits he/she just started watching it, whereas Derek confesses he binge watched the first two seasons in a week.
- The Handsome Stranger for his part doesn't want to hear any spoilers because he is only at the Battle of Wolf's Mouth.
- As of August 31, 2018 The Crown & The Flame, Book 3 along with the first two books of The Crown & The Flame series, Veil of Secrets, Endless Summer, Book 2 and Most Wanted, Book 1 have had the thumbnails of their book covers updated; in this new version, the title follows the same style like the first two books, 'Book Three' no longer appears with the title, and the position of Dragon Dom was slightly altered.
- In The Freshman, Book 4, Chapter 4 and in Perfect Match, Book 1, Chapter 3, a movie poster version of this cover can be seen in the background.
