描述
Spying, space aliens, high-tech gadgets, and loads of laughs—what more could middle-grade readers want? In the first book of this new series, ten-year-old Cassie encounters a family of aliens from Triminica. With Cassie's help, the aliens' son poses as a fifth grader, and the two solve their first mystery after the Triminican's snooty robot disappears.
