A Jock for Matthew by Declan Rhodes

Matthew, the youngest of four brothers in the Sanderson clan, feels invisible in a family of local celebrities. Known only as “the tall, skinny one,” Matthew’s the brainiest of the bunch and signs on to help conduct a research project led by a tyrannical, but well-known, professor as a short track to fame and fortune in his field.
Soon, Matthew meets test-subject Shawn Trent, a handsome, muscular, blond college football offensive lineman. Shawn is an English literature major fond of quoting Walt Whitman to his teammates. He’s all muscle laced with sensitive smarts, and he’s in the closet—for now.
