The Interns by Birdie Jones

Maya Hendricks, a no-nonsense law student, has a plan: graduate top of her class, move to a big city, land a job with a top intellectual property firm, and make partner by her thirtieth birthday.
Reed Stanton, a former small town sheriff’s deputy, also has a plan: get through his final year of law school, move back home, secure a job in the district attorney’s office, and clean up corruption in his hometown.
A summer associateship at a prestigious law firm in Atlanta brings them together, and first impressions are…not good. At all. Once they start their case, however, they are surprised to find how well they work together, and even more surprised by what they discover about each other along the way. It turns out that Maya has a heart bigger than any of the cities she dreams of moving to, and Reed has intelligence and drive that belie his humble roots.

Neither expected to meet their match, but it happened, and now they must figure out how, and even if, a relationship fits into their plans.
