What are some good books that are not a romance novel?

'The Notebook' by Nicholas Sparks can be considered in this category too. It's a very moving love story. The male lead tries to persuade the female lead to remember their love and relationship through the story he writes in the notebook, in the face of her memory loss due to illness.

There might be modern retellings of 'Emma' in the romance genre. For example, some authors take the basic premise of the character Emma and place her in a contemporary setting, like a big city or a small town in the present day. These books often keep the essence of the original, such as Emma's strong - willed nature and her journey in love and self - discovery.

One popular one is 'To All the Boys I've Loved Before'. It tells a sweet story of a teenage girl whose love letters get accidentally sent out. Another is 'The Fault in Our Stars', which is a heart - wrenching romance between two teenagers with illness. And 'Simon vs. the Homo Sapiens Agenda' is also great, dealing with teenage love and self - discovery in a modern high - school setting.

'Attachments' by Rainbow Rowell is also a wonderful option. The story is set in the early days of the internet and the male lead has to read people's work emails for a living. He falls for a girl through her emails without ever having met her. It has a unique charm and is quite humorous in the way the characters interact and develop their relationship.

'Eleanor & Park' by Rainbow Rowell is a wonderful adolescence romance novel. It shows the relationship between two misfit teens who find solace and love in each other on the school bus and in their shared love for music and comics. It beautifully portrays the intensity of first love during adolescence.

Some mystery novel romance books worth checking out are 'The Da Vinci Code' by Dan Brown. There is a bit of a romantic sub - plot between the main characters as they race to solve the mystery. 'And Then There Were None' by Agatha Christie also has some underlying romantic elements in the relationships between the characters as they are trapped on the island and the mystery unfolds. 'The Name of the Rose' by Umberto Eco combines a medieval mystery with a budding relationship between the main characters that adds a touch of romance.

One of the popular ones is 'Twilight' by Stephenie Meyer. It's a classic in the vampire romance genre, which tells the love story between Bella and Edward, a vampire. The series has been widely loved for its unique take on vampire lore and the intense romantic relationship.

You might enjoy 'Me Before You' by Jojo Moyes. It's a touching romance that explores deep emotions and life choices. The characters are very relatable and the plot keeps you engaged throughout.

You can't go wrong with 'Jane Eyre' by Charlotte Bronte. It has elements of mystery, a complex love story, and a strong female lead. 'Dear John' by Nicholas Sparks is another. It tells a story of love tested by distance and circumstance. And 'The Time Traveler's Wife' by Audrey Niffenegger is an interesting take on love and time, where the hero has a disorder that makes him travel through time, and his relationship with his wife is both beautiful and challenging.

Another good one is 'Outlander' by Diana Gabaldon. It has a time - traveling aspect to it. Claire Randall travels back in time and falls in love with Jamie Fraser. The story is rich in historical details and their relationship is complex and full of love.
