Looking for a middle grade book (1990s-2010s) about a boy whose dad loses his job at the planetarium
from what I remember of the plot, the main character was a boy named artie or something similar whose dad loses his job at the planetarium and so his family has to move. another important part of the plot was the boy's new neighbor who he assumed was a creepy murderer but who just has a passion for the stars.
his best friend is a girl named Priya.
the book had Mars on the cover, included weird descriptions like calling the friend's mom a "rainbow," and complained about raisins in cookies like most middle grade books
any ideas?
