CHADRON, Neb. -- It is normal for brothers of any age to have disagreements. What isn't typical, though, is brothers who write a novel together. However, that's exactly what Lincoln Proud, 24, and Ethan Proud, 20, both of Pinedale, Wyoming, did.

"We had our share of arguments and fights as brothers always do, but when it came to our writing we always found a middle ground," Lincoln said.

That middle ground led to an unlikely by-product, "Rebellion," a medieval fantasy novel the brothers wrote. The novel will be available to the public on May 27 through tatepublishing.com.

"We began writing it when I was in seventh grade, but never really tried to finish an entire book. We wrote and re-wrote a lot," Ethan said.

The medieval fantasy story is a product of the many drafts that Ethan and Lincoln attempted to finish over the years. "Rebellion," which is 388 pages, takes place in the mythical country of Durthia and tells the tale of a rebellion led by Jergle, a Duke of the south, against a corrupt king.

Along with literature, competing in track and field at Chadron State College is something that runs in the Proud family. Lincoln, who graduated from Chadron State in 2013 with a sports and recreation degree, owns the school record in the 400 hurdles, and Ethan, a sophomore, currently competes as a sprinter for the Eagles.

Their mother, Jenifer, still owns the 55-meter and 100-meter sprint records at CSC, and their father, Larry, was also a successful track athlete for the Eagles.

Whether it is on the track or on a blank white page, the Proud brothers are always striving to leave their mark.

Even now, as their first published book is set to hit the shelves, the brothers are tinkering away at a sequel.

"Whether or not this one succeeds, we plan on continuing to write the sequel. Hopefully, "Rebellion" is well-received," Ethan said.
