Peek-A-Boo. Super Short Super Hero Instalove Romantasy, #3

Xavier Storm can go invisible at will. It makes his magic show thrilling to the audience who has no idea he's a lab created supernatural experiment. As a Castor strain variant, he wants to make sure the normal humans he's entertaining don't realize who he really is. But when he literally bumps into another invisible supe, his carefully constructed world is turned upside down. Ari Cardonne, a spy for the Pollux strain's Legion, is on a mission to ensure that the norms never again create or harm supes.
Xavier is her other half, created by the Aethor Institute. However, their different strains make them wary of the dangers that their relationship could bring. But when a new outbreak of supernatural attacks threatens to incite violence against supes, Ari and Xavier have to trust each other to work as a team to stop the violence, as well as to let each other into their hearts.
