I've chased down a ridiculous number of melodramatic romance titles over the years, and 'Betrayed By Husband Stolen By Brother In Law' is one of those phrases that tends to pop up across several self-publishing platforms. From my digging through reading apps and comment sections, the tricky part is that this exact string of words isn't always a single, trademarked book by one famous author — it's a trope-y headline that a bunch of writers use, especially on sites where people serialize their stories. That means you can often find multiple different tales with the same or very similar title, written by different pen names on places like Wattpad, Webnovel, or indie KDP listings on Amazon.
If you're hunting for the author of a particular version you read, the practical way I go about it is: search the exact phrase in quotes on Google and add the platform name (e.g., "'Betrayed By Husband Stolen By Brother In Law' Wattpad"), then open the top results and check the story page for the author/pen name and profile. For Kindle or paperback editions, look for the ISBN or the Amazon author page — the product listing usually gives the author's real or pen name and links to other works by them. On free serial sites, the comments and chapter footers often include an author’s handle; that’s where I’ve found the clearest attribution more than once.
Personally, I’m fascinated by how these revenge/redemption/forbidden romance setups travel between platforms. Sometimes the same story migrates under slightly altered titles when fans mirror it across sites, which is why a single title search can show different names. If I had to give one takeaway: there might not be a single definitive author unless you can point to a specific edition or platform. I’ll happily nerd out with you about whichever version you found — the plot beats are such comfort reads, and hunting down the original author always feels like a mini mystery worth solving.
