Maria, that's the order that I wrote them in. There is some overlap from certain stories to the next. I.E. Marty's two stories start after chapter 8 of Starfire and Sunstorm, and Vicky's starts after chapter 10 of S&S. And then Timestorm starts between chapter 7 and 8, IIRC.
That's what happens when time travel is involved, I guess.
Reading them in that order is not a problem due to the fact that each story is a stand-alone, for the most part.
