Keeper

The fifth novel in the Exiled Guardians MC Series is "Keeper," written by Hope Ford. The protagonist of the tale is Lilly, who at the age of eighteen discovered her brother, the President of the Exiled Guardians. For protection, he sent her to college, but now that she's returned, the one man she's been thinking about for years is still there. Every other brother in the club forbids the man, Keeper, who is the President's younger sister. As Lilly reappears in the story (older and more gorgeous than before) all bets are off.
