So when he is approached by Raglen James--a con artist who has been kicked out of the secret psychic organization The Talamasca, good guys with a computerized record of all major evil events caused by nasty spirits, and who has learned the trick of body switching--Lestat is fatally seduced into switching bodies with James for two nights and a day. Sweet-smelling, cruel, proud, self-pitying, death-proof, snotty, multi-billionaire honcho vampire Lestat finds himself in the tall, handsome body of a man who bears every human frailty, suffers proneness to a killer cold that lands him in the hospital, has mortal fears by the dozen, synapses much slower than Lestat's, sloshy flesh that twists with hunger, always feels leaden, and must descend to the horrid stinks of the toilet. He's robbed blind by James, a great hacker thief, and falls in love with a Catholic nun--while James, on a blood-flying rampage, won't give Lestat his body back.
While the queer vampires of Anne Rice's The Vampire Chronicles are well known, this book centers on a gay mortal who interacts directly with queer vampires, Louis and Lestat.
While this book does provide an unusual transformation, it is nowhere as good as the first two, nor even the third.
