In this funny, big-hearted friendship story, perfect for fans of Wendy Mass and Linda Urban, twelve-year-old Edie and her impossibly cool cousin, Rae, set out to complete a mysterious list of "Good Ideas for Summertime" that their eccentric late grandmother wrote back when she was their age. But good ideas? Most of them seem like bad ideas. Reckless. Foolish. Ridiculous. Still, by accomplishing everything on the list, rule-abiding Edie feels certain that she can become the effortlessly brave adventurer she dreams of being, just like her daring cousin and bold grandmother. For this one summer at least, bad ideas are the best shot she has at becoming who she wants to be. Bad Idea Number It's time for a new set of rules.
