It is a bit hard to describe but I will try. It is on the ground floor. When you come in through the main entrance from the car park, go straight down the main thoroughfare. As you move along, you can turn right at the second right-turn amongst the shoplots (this is the part I am not sure as I don't count them!). Go down the alley a bit and you should then see the shop on your left.

It is somewhere on the right side of the mall and given the small size of CM, you can easily find it. Otherwise there is always a friendly concierge at the entrance as this is a tourist spot.

You will see shelves and shelves of books piled inside. I really hope you manage to find it without any trouble. I just borrowed Greg Egan's Halo - THe Forerunner Trilogy, I hope they get Bk 2 next. And somehow I managed to find a copy of The Tiger's Wife by Tea Obreht.
