Top 10 Author Duos I'd LOVE To See Write Together

Top Ten Tuesday is a weekly meme hosted by The Broke and the Bookish 

It's Top Ten Tuesday time! And this week's Top Ten Tuesday topic is: Top 10 Author Duos You'd LOVE to See Write Together! This took some brain-wracking, but I think I've come up with a fairly good list. I sort of cheated and a few authors more than once, but I think you'll understand when you see which authors I used more than once.

1. Leigh Bardugo and Victoria Schwab. Two incredible authors all on their own; just imagine what they'd be like if they wrote a series together?!
2. Victoria Schwab and Maggie Stiefvater. Same case as the first one. Two amazing authors on their own; put their genius together and the world might explode.
3. Jonathan Stroud and Anthony Horowitz. I know, they both kind of write books entirely different from one another, but I would love to see what they could create together!!
4. Cat Winters and Ruta Sepetys. Both historical fiction writers, BUT - Cat Winters always does some supernatural twist on her books. So what could my most favorite supernatural history author and historical fiction writer create together?
5. Ruta Sepetys and Elizabeth Wein. To be honest, that pairing seems like a no-brainer. They both favor WWII and are both very emotional writers.
6. Jennifer A. Nielsen and Caroline Lawrence. After reading Jennifer's Mark of the Thief book, I'd love to get these two Middle Grade ancient world writers together to write something amazing.
7. Kendare Blake and Lish McBride. If you've read any of their books, you won't have to ask why.
8. John Flanagan and K. M. Grant. I'd love to see what these two could do in terms of historical fiction.
9. Sharon Cameron and Gail Carriger. Victorian/steampunk galore!
10. William Ritter and Sharon Cameron. Same reason!
