When he arrives home from a long stint in the hospital after losing his right arm to an IED blast, Sergeant James Miller certainly doesn't expect his keys not to work and a strange man answering his door, only to learn his boyfriend has dumped him. Yet that's exactly what happens, and James is just happy that he can count on his old platoon buddy to have his back, and a spare bedroom he can use until he gets on his feet. Horace Grundy the third-"Horse" to anyone who doesn't want to get his butt kicked-is retired and has a tidy house on the beach that he calls home. The place isn't big, but he figures there is plenty of room for James, even if he has always fancied the man. Thankfully, the two of them fit together well, and soon the roommates become more. But James's past isn't ready to let go of him yet, and the new lovers are caught off-guard when James's ex-boyfriend suddenly reappears in his life. Can James and Horse's new relationship weather the storm?
