Nico di Angelo and William Solace are dating and practically no one knows (somehow). The two of them have their ups and downs like every couple, but then Nico and Will get in a fight and Nico disappears that same day. It takes Will and a couple others on a journey to the Underworl to search for him. What will happen to him? What will happen to their relationship? What will happen to him if Will doesn't find him? And what will happen if he does? Could it only make things worse for the young gay couple?
