It's possible that 'The Price of Salt' was also among the popular ones. Its exploration of a same - sex relationship in a time when it was less accepted in society gives it a certain poignancy. The way the characters interact and the slow - burning nature of their relationship attracted many readers.
I'm not sure which ones were the most popular exactly, but 'Ash' was quite well - received. It's a fantasy - inspired lesbian romance that combines elements of fairytales with a modern - day love story, which made it appealing to a wide range of readers.
One of the most popular is probably 'Carry the Ocean' by Heidi Cullinan. It's loved for its well - developed characters and their emotional journey.
'Tipping the Velvet' by Sarah Waters is extremely popular. It tells the story of a young woman's journey through different relationships and her discovery of her own sexuality. The characters are well - developed and the Victorian setting adds a lot of charm.
The settings could vary widely. Some might be set in modern urban environments, where the characters navigate through the challenges of a fast - paced, often judgmental society. Others could be in more rural or small - town settings, where the sense of community and secrecy play important roles in the love story. The language used in these novels is usually rich in emotion, to really convey the intensity of the relationships.
One great book from that list could be 'Ash' by Malinda Lo. It has a really engaging story with well - developed characters and a unique take on the lesbian romance genre.
One popular one is 'The Price of Salt' which has been around for a while but has gained more popularity recently. It was quite revolutionary for its time in portraying a lesbian relationship.
Another one might be 'Fingersmith' by Sarah Waters. Although it may not be strictly from the 2015 list but is a well - known lesbian romance. It's set in Victorian London and has a thrilling plot full of twists and turns. The love story between the two main characters is beautifully portrayed against the backdrop of a society full of secrets and intrigue.
Emotional depth is another key feature. Since they are romance novels, there are intense emotions involved. The relationships between the female characters are often filled with passion, love, but also the pain of misunderstanding or social obstacles. These elements together create a rich and engaging reading experience for those interested in lesbian - themed romance fiction.
'Leah on the Offbeat' is a great one too. It's a follow - up to 'Simon vs. the Homo Sapiens Agenda' and focuses on Leah, who is bisexual. But it has a really sweet and engaging lesbian relationship storyline that's full of the normal teenage angst, family drama, and of course, love. It's a really relatable read for many.
'Carmilla' is a well - known one. It was written a long time ago but still holds up as a classic lesbian romance. It has that gothic horror element combined with a relationship between two female characters.
I think 'The Hunger Games' was quite popular. Although it's mainly a dystopian novel, there are elements of romance that made it appealing to a wide audience. The relationship between Katniss and Peeta was a major draw.
