@laani2000 First of all, thank you so much, I'm so glad you liked The Puppeteer (I think for a lot of people the mix of thriller and romance is a big no-no and they don't give it a try, so I'm incredibly grateful you gave the book a chance)!
If you like the "Mafia Romance" genre, there are quite a few on the @MafiaCommunity profile, there is also a "dark romance" profile somewhere on Wattpad (I'll have to search around a little for that one, but I'll post the link as soon as I find it).
One of my favorite romance/fantasy/paranormal stories was "The Tale of Tugarin" by @AndreaVonReding - The author is on hiatus until January, but she'll bring the book back then.
If you want to try an entirely different genre, there is for instance "mirror Image" by Sandra Brown ( @sandrabrown_NYT ), she's a New York Times bestselling author, so the quality of the work is according.
So the above is what I can tell you from the top of my head, but let me do some more thinking (and browsing) and I'll certainly come up with a few more books!
