A girl resists growing up by hiding from some unpleasant truths At the beginning of summer, thirteen-year-old Cassie is witness to a disturbing sight. At a party she spots her sister"s husband, Mickey, in the arms of another woman. Could it really be him? And with her sister about to give birth to their first child? When Cassie confronts Mickey, he claims it must have been his double. Though it"s hard to believe him, Cassie struggles to do so with all her might - she has always adored Mickey and doesn"t want to think he could do anything wrong. For distraction Cassie has the company of her good friends Megan and Tommy, along with the refuge of the Spindrift, the beautiful old seaside house where she lives with her mother and grandmother Emma. But even the security of home is threatened when Emma, who runs a bed-and-breakfast out of the Spindrift, decides she"d like to sell the house. Cassie will learn this summer that she can no longer cling to childhood to escape from the unpleasant things that sometimes happen in families.
