Whatever Wednesday - We Are All Made of Molecules by Susin Nielsen

 I bought this book for a dollar at our local  Bedford  library  book sale.  I did not realize it was  a YA book. Turned out to be a pleasant treat.  We Are All  Made of  Molecules by Susin Nielsen captures the  ups  and downs  of middle school perfectly.  

Stewart  is thirteen - brilliant but  clueless. He's been upgraded to  ninth grade, but kinda waiting  for  puberty to hit. His mom died and he and his dad have been hanging  in  there. 

Fourteen  year  old Ashley is the HOT Girl, but not the brightest bunny. Her father moved out, for reasons Ashley would rather not  advertise.  

To her mortification, her  mom and Stewart's dad are a couple and now Stewart is calling her his "sister" and lives in  her house.  And he's in the same grade.  And she could just die...

Every other chapter covers ninth grade life as per Stewart's viewpoint,  and then Ashley's.  It's funny and charming and poignant.  Reading it  as an adult, I could relive the absolute torture of ninth grade. Well done!
