Sonata by Moonlight (Heroes and Half-Notes #1)
A.E. Easterlin

Her first assignment is in her hometown, and she isn't the only one who has come home. Brodie Miller is back, hot as ever but a little broken from his own tour of duty. Can the magic of music in the moonlight and a steadfast love heal his mind and heart? When he sees her as a woman and not his buddy’s little sister, Brodie could fulfill her dreams—and his own—or leave her achingly lonely forever.
