The Killing Moon

So i just finished up N. K. Jemisin's "The Killing Moon", which was pretty good. It did take a little while to get into, in large part because it's modeled after Egyptian culture and it took me a little while to get the hang of the names.

One thing that's bugging me a bit though is the orbital dynamics of the world.

The planet has two "moons", the Dreaming Moon and the Waking Moon. The description makes it sound like the Dreaming Moon is actually a gas giant. However i'm having a tough time figuring out how to make that work.

And also, if Dreaming moon rises and sets that means that the world is _not_ tidally locked to the gas giant. I wonder how that's possible? How many moons of gas giants _aren't_ tidally locked?

I dunno, this is all making my head hurt =P
