Yeah, you can find it on Amazon. Young adult novel, official and canon, about Team CFVY in Vacuo one year after the Battle of Beacon.
Edit: found the Amazon listing.
After the Fall (RWBY) https://www.amazon.com/dp/1338305743/ref=cm_sw_r_cp_apa_i_5X3ACbCNKKXRF
As others have pointed out, team CFVY are getting an entire book dedicated to them and their adventures in Vacuo. That is where their current future is heading. (Huge sword guy = Yatsuhashi for your reference) Beyond that, we'll see. It'll likely depend on how well the book does.
Hell, considering that team SSSN is heading to Vacuo as of this volume, I wouldn't be surprised if they made a cameo in the book.
With this in mind, here is the link to the book listing in Amazon. It should be out by July of this year, if you don't mind preordering that long.

Thank me later. Also, every time she uses one of said weapons, she loses it, so it's basically a one-off per use, which is why Coco tells her "not to waste" it during the V2 finale fight.
Found it. Obviously change the address depending on where you live so you get the Amazon closest to you.
It's called "After The Fall", and it comes out July 30 2019. You can already preorder it on Amazon, and probably your local bookstore.
