"Abby is twice exceptional - she is gifted in math and science, and she has ADHD. Normally, she has everything pretty-much-sorta-kinda under control. But when Abby makes one HUGE mistake that leads to "The Night That Ruined My Life" or "TNTRML" she lands in summer school. Abby thinks the other summer school kids are going to be total weirdos, but as Abby learns to communicate better and finds friends who love her for who she is, she discovers that her biggest weaknesses could be her greatest assets. -- Adapted from the book jacket.
