It was about a girl, and she lives in this castle in the desert. It kind of has a Persian feel to it. Somehow she escapes and befriends Nomads. She falls in love with their leader and is happy, but then she is captured and taken to a tropical rainforest castle that changes and shifts. There is only one man there and she starts to fall in love with him, but somehow escapes from there as well.

Then she is taken to another city where this old haggish woman rules and does something with dice. She wants the girl to be the dice woman and take her place, but of course the girl doesn't want to.

Her first lover (the nomad guy) comes and rescues her. I know it has a happy ending. There is a robot type thing in some of it. And the cover is a dark haired girl in royal blue with a desert in the background.

Does anyone know this book!? Please help me remember! I know I'm forgetting some pieces, but that is the general. And it was a three in one book.
