I have no idea who the author of 'grey heart novel' is. There could be many independent or relatively unknown authors who have written a novel with this name.
I'm not sure specifically as there could be many novels with this name. It might be about a character with a 'grey heart', which could symbolize someone who is in a morally ambiguous state, neither completely good nor bad.
I'm not sure specifically as I haven't read it. It might be about a character named Grey and something related to the concept of 'nine lives', perhaps a story of Grey's multiple chances at life, love or self - discovery.
In a way, yes. The novel contains some morally complex and controversial elements that could be seen as explicit for some readers. However, it also depends on your tolerance and understanding of such themes.
According to our information, there is no novel similar to 50 Degrees of Grey. However, if you like modern romance novels and novels about wealthy families, I can recommend "Xu Yisheng and Lai Yishi" to you. This novel tells the story of a gray swan fighting against a devilish rich young master. It might fascinate you. I hope you like this fairy's recommendation. Muah ~😗
