Wizard Undercover: Book 2 of the Rogue Agent Novels by K. E. Mills
There may be trouble ahead . . .
Wedding bells are ringing for the constantly battling nations of Splotze and Borovnik, and the upcoming royal nuptials could at last put an end to their dangerous hostilities. But in a development that hardly bodes well, one of Gerald's fellow janitors goes missing - after delivering a dire warning of danger surrounding the marriage treaty. So Gerald must embark on a dangerous mission to uncover the troublemakers, before wedded bliss becomes international war.
But going undercover isn't as easy as it looks, even with Melissande and Emmerabiblia for camouflage. Soon Gerald finds himself fighting for his life as well as world peace.
