Survivors of the Virus Storm — Diana Sheridan

After a handcrafted, weapons-grade virus mutates and decimates nearly all the world's population, Aaron fears he's the only one left. He is overjoyed to discover another live human, Keith, who also happens to be gay, as is Aaron. Aaron travels to Indiana to live with Keith, with a plan to at least be housemates, but they find they are very compatible with each other and quickly become lovers. It takes some getting used to the new world, and their adventures include looting stores whose owners are dead to get needed items, and chasing off bands of feral dogs whose owners have died and left them hungry. The world as they once knew it is vastly and irrevocably changed. Can the two lovers build a new world for themselves...and will their search turn up any other survivors, or are the two of them all that is left?
