The Brilliant Fall of Gianna Z

Gianna Z just can't help it, time keeps sleeping away as the deadline for her leaf collection project looms ever near.  Will she be able to finish it in time to get her grades up so she can still attend the track meet?  And why is she the only one who seems to notice that her grandmother's forgetfulness may be getting worse?  This book would be a great read for anyone who has to do a similar project.
