From Goodreads:

Deep in the heart of Texas - Austin to be precise - lies the Court of the Jade Chimera, which is presided over by Agnes, a drag queen of formidable bearing. For many years, Agnes has been holding in check the homophobic Brother Earl, a charismatic Oklahoma radio preacher with his own university, with the existence of a set of photos depicting Brother Earl in the midst of some rather "unchristian" activities. Those photos, however, have slipped from Agnes's grasp and Brother Earl is now using his pulpit to call down a jihad upon gays. Now Agnes must put in motion her pawn, a very attractive young man named Jim, who must go into the heart of enemy territory to recover the missing photos or, if need be, seduce Brother Earl and replace them. Filled with an amazing cast of characters - Hell's Fairies, a gay motorcycle gang; Crumbelly Croissant, a lavender bluesman and singer of the classic song "I Left My Mojo in My Other Bag"; and Agnes herself, a six-foot-six drag queen with foot-long lavender nails - Pawn to Queen Four is a tour de force, an astonishing comic novel that will delight all.
