Holly Farb and the Princess of the Galaxy by Gareth Wronski

Holly is the smartest kid in the class until the new student shows up.  He knows even more about faraway galaxies than she does.  Feeling down trodden, she decides to eat her lunch in the playground.  That was a bad idea because there are these funny looking aliens looking for a princess and they think she must be it...

Aladdin and Edelweiss allowed me to read this book for review (thank you).  It will be published June 6th.

Holly, the new kid, and her teacher end up being kidnapped and taken out into space.  It would be exciting if it wasn't so dangerous and scary.  When it turns out the new kid was actually the princess in disguise, it gets even more dangerous.

This is space opera for young ones.  There are crazy characters, weird aliens, the pirate leader wants to kill the princess, the leader of that galaxy is a bunny and they meet a bounty hunter.  It's busy, full of nonsensical fun, and keeps you reading.  There's nothing too deep about this story but it is a fun read.  It'd be great for middle graders.
