Nate's Last Tango (Nate and Cameron #2)
Kevin Klehr

But when Nate decides to visit his friends back in Sydney, Cameron suggests they break it off for a while. Cam’s cross-dressing butler is not impressed, and with the help of his lesbian aunt, they drag Cameron down-under to sort out his relationship and take in the sights of Mardi Gras!
With Nate at a loss to what went wrong, he faces the dim reality that love may have run its course.
