This isn't so much as a request for a recommendation but more of a search for a book. It is in the tween section and I think it would've been made in the 90's-2000's. From what I can remember, it's about a group of people all stranded in space. In this book (I think it's a series) two aliens infiltrate the ship posing as humans. They pose as a teenage boy and girl and shenanigans ensue. I know this isn't really the place to ask, but I'm desperate.
