Feel the Burn by G.A. Aiken

                                     

Gaius and Kachka have some interesting conversations:
                      “So you’re not going to get Zoya out of my room?”
                      Kachka stared at him. “Do you really want to sleep in bed that Zoya Kolesova just effed in?”
                    “Excellent point,” he conceded.
                   “Besides, we can eff here under stars.”
                   Gaius blinked. “We can?”
                   “Why would we not?”
                   “Well . . .” he began. Then he finally said, “I have no argument.”
I really loved this book, there was so much humor and story.
