Vincent and his childhood friend Eric became a couple after Eric initiated him into the pleasures of the Playhouse, a refuge for men to act out their submission/Domination fantasies. Their relationship is warm and loving, but not exclusive. Eric is a "switch," and since Vincent is a submissive, Eric sometimes looks to his own Dom, Anton, for satisfaction-causing Vincent to feel jealous and insecure. Then Anton's uncle dies and Dimitri-Anton's twin and a troubled, surly, irresistibly sexy version of his brother-comes for a visit. When Dimitri sets his sights on Vincent, ridiculing his supposed sexual passivity, Vincent begins to wonder: is he really a sub, or a switch, like Eric? In the first blush of their relationship, Vincent and Eric reveled in their connection, calling themselves "two of a kind." Perhaps they are also alike in ways that challenge their current power dynamic. Two of a Kind continues the story of Vincent and Eric, which DC Juris began in his novel, Finding Sanctuary.
