Encroachment (Coach's Shadow Trilogy #2)
Monica DeSimone

Jackson Alexander knows all of the past ugliness that occurred, and although he has loved Claire since she was fifteen years old, he always settled for the friendship that she offered. Now, twenty-three years later, he is back and getting the chance he always desired.
Claire still finds it impossible to let any man into her life, but he won’t be deterred. This time he is not letting her push him away. Even if it means getting a flag on the play for encroachment, Claire will ultimately be his.
