Stars of Mithra by Nora Roberts

I've read the first two books in this series a month ago. It was compiled in one book entitled STARS. I thought the last installment will be coming only in a compiled edition with another story but when I visited a book store, I saw that the first two were separated. Honestly, I went crazy right there and then anticipating that I'm gonna be able to read the last book. Unfortunately, there wasn't. The store doesn't have it yet. =( *sighs* From time to time I drop by to that store before I go home just to check if they have it already. And as always, I end up buying a book I can spend my travelling and boring hours with. ^^
