Ada Lace and the Impossible Mission by Emily Calandrelli gives this science loving heroine a formidable task. She is part of a group project that has been potentially sabotaged, so she plans a break into the teacher's closet to check and make sure all is well with her team's work. Among other things, she must evade a clever parrot, use her lock picking skills and boot up her robot George--while trying to keep her team on course. The appendices explain the real science behind the hurdles she has to overcome. The story does allow for a certain amount of questionable behavior, but never without consequences.
