Don't forget about 'The Selection' by Kiera Cass. It's about a girl who enters a competition to marry a prince. There are many twists and turns in the romance department as she navigates her feelings for the prince among all the other competitors.
'FBI Love in the Line of Duty' is quite good. It shows how two agents deal with their feelings for each other while being in high - pressure situations. It has a lot of action and the romance is really sweet. They support each other both in their personal and professional lives.
'Vicious' by V. E. Schwab can be considered. It has characters with extraordinary abilities and a complex relationship that can be seen as a form of romance. The way the characters' powers interact with their emotions and their connection to each other is really fascinating. There's a lot of depth to the story and the relationships.
One great princess romance novel is 'Ella Enchanted'. It tells the story of Ella who is cursed with obedience. Her journey as she tries to break the curse while falling in love with the prince is really engaging. The characters are well - developed and the world - building is charming.
Well, 'A Crown of Wishes' by Roshani Chokshi is really good. It has a princess who is brave and intelligent. The world - building in this novel is amazing. Then there's 'The Goose Girl' by Shannon Hale. It's a beautiful retelling of the fairy tale, and the princess in it has to find her way back to her rightful place through her own strength. 'Princess Academy' by Shannon Hale is also a great pick. It shows how a group of girls are trained to be princesses and the journey of one girl in particular.
I'd say 'The Unhoneymooners' by Christina Lauren. The whole premise of two enemies having to go on a honeymoon together is just ripe for comedy. The characters' constant bickering and the unexpected situations they find themselves in make for a really funny read.
'Ella Enchanted' is also great. Ella has been given the 'gift' of obedience, which causes all sorts of problems. Her relationship with the prince is a sweet and complex one as she tries to break free from the curse and find true love.
Meg Cabot is quite well - known. She has written many books with princess - like characters in modern settings. For example, in 'The Princess Diaries' series, Mia Thermopolis discovers she is a princess and has to deal with all the chaos that comes with it, including a budding romance.
A great one is 'Cinder' which is a modern take on the prince and princess romance. Cinder, who is like a modern - day princess, meets the prince in a rather unusual way. The story is set in a futuristic world and combines elements of science fiction with the traditional prince - princess love story.
One popular one is 'The Princess's Guarded Heart'. In this novel, the bodyguard is a brooding yet noble character who is initially just focused on his duty to protect the princess. But as they face various threats together, their relationship deepens into love. Another great read could be 'Protecting the Royal Princess', where the bodyguard has a mysterious past that adds an extra layer of intrigue to the romance.
One popular modern princess romance novel is 'The Royal We'. It tells the story of an American girl who falls in love with a prince while studying in England. Another is 'Red, White & Royal Blue' which features a romance between the First Son of the United States and a British prince.
