Casper is in advertising and works in a firm where his immediate boss, Blaine, is gay and engaged to Spencer. Spencer has bi-sexual brother Slater, a Ranger in the military, who took one look at Casper and knew he was the man for him. Casper, however, is never going to give into the pressure Slater is putting on him for a date. He was going to marry a soldier, Mason, but he was killed in action. Mason's family wouldn't allow Casper to go to the funeral so he grieves in private every Memorial Day, Veteran's Day, holidays and Mason's birthday. He can't lose a love like that again, and he can't move on from Mason.
Casper, however, has not realized saying no to Slater is not going to make him go away. Mason sends a stripper to Casper's work, he sends singing telegrams, he sends the movie Casper, he puts Casper's face on the side of a truck...get the idea? Slater is home on leave from a combat zone but still has a mission - Get Casper. Everyone is in on it and the last straw for Casper is when Slater is hired as a male model for a campaign he has been working on for so long - so he gives in gracefully.
Slater and Mason had used the same tactics to get Casper which started the wall falling to let Slater in and they become lovers. Slater returns to combat but tragedy strikes his unit and things won't ever be the same again.
It is a nice read, bit tear jerker material, bit laugh material. The third in the Men of Manhattan series and I think they need to be read in order to make sense because there are a cross of characters.
