Sorry, I'm not familiar with Ramanichandran's novels well enough to recommend the most famous ones.
I think 'Kadhal Parisu' is very famous. It has a simple yet profound exploration of love that has appealed to a wide range of readers.
Another notable work is 'Ponniyin Selvan'. This novel is set in a historical context and Ramanichandran weaves a tale full of drama, politics, and relationships. The detailed descriptions of the era and the characters' struggles make it a great read. It has also been highly praised for its ability to transport the reader to a different time and place in Tamil history.
I'm not entirely sure which specific novels by Ramanichandran are most famous. However, his works might often deal with themes like relationships, family, and the cultural context of the region he hails from. Maybe he has some novels that are centered around the local traditions and how characters interact within those cultural frameworks.
One of his well - known novels is 'Kadhal Parisu'. It's a story that beautifully captures the essence of love and relationships in a very engaging way.
His novels often have strong character development. For example, in many of his love - based novels, the characters grow and change as the story progresses.
Another option is to look for any awards or honors that Ramanichandran has received for his novels. The ones that are recognized in such a way are likely to be among his best works. It could also be that his novels which have been translated into multiple languages are very popular and potentially among his best, as they have a wider appeal.
Since I don't have access to the exact sales figures of Ramanichandran's novels, it's difficult to say which are the best - selling ones. But novels that have a strong emotional core, such as those that tell a heart - wrenching love story or a story of family reunification, are often more appealing to a wide range of readers. His novels that are set in unique cultural landscapes and explore the nuances of that culture could also be very popular.
I'm not sure exactly which are the very latest ones. But Ramanichandran is known for his engaging stories. One of his popular works might give you an idea of what to expect from his recent novels. His novels often deal with human relationships and the nuances of life in a very relatable way.
Another great work could be 'Ponniyin Selvan'. This novel weaves a complex web of relationships and love stories set in a historical backdrop. The characters are well - developed and the romantic elements add depth to the overall plot. It has been highly regarded among Tamil readers for its engaging narrative and the way it presents love and loyalty.
Since I don't know much about ramanichandran's romantic novels directly, you might try asking in some book - lover communities or forums. People there are often passionate about sharing their favorite reads, and they might be able to point you to some of ramanichandran's great romantic works.
