Sammy Keyes Mysteries
by Wendelin Van Draanen

Move over Nancy Drew, Sammy Keyes is on the case!  Sammy Keyes
is a hard-nosed tough gal.  She has to be.  Her mom has abandoned
her, and she lives with her grandmother in an all adult community. She
has to sneak into her home by the fire escape! Then there is the whole
problem of being in the seventh-grade with the horrid Heather Acosta.   
With her smart mouth wise-cracks and her stubborn nature, Sammy
just seems to attract trouble and stay in it, but she sure has a knack for
solving mysteries!
