Nope, but there is a Lori Foster series that has been or is in the middle of being re-released, that features Gabe, Morgan, Sawyer and Jordan that's called the Buckhorn Brothers' series.  

Thank you Renee will check that one out

That series has been reissued many times over the years.  You can probably get them through PBS easily.  There's more than a few Lori Foster anthologies with these stories in them.  First they came out singly with the brother's names as the titles. Then they started adding them to compilation books under different titles.

Lori Foster's series is the Buckhorn Brothers.  Susan Mallery had a Buchanan series- 3 books in that one.
