Information on the book Flipped by Wendelin Van Draanen?

[I'm not telling]

I have to do a summer book report, and I need a list of the characters.
This is what I have:
Bryce Loski
Julianna Loski
Bryce's grandfather-Chet? Full name please
Bryce's mother-Patsy? Full name please
Bryce's father-Rick? Full name please
Juli's mother-??? Full name please
Juli's father-Robert? Full name please
Bryce's siser-Lenetta? Full name please
Juli's 2 brothers-???
Bryce's friends-Garrett?
Juli's friend-???

I have who they are in the book, but can anyone provide me with the actual names of the characters? I got the book at the library, so I don't have it. You don't have to know all the characters, but any that you remeber please!
