From two-time Newbery medalist Lois Lowry comes this warm and resonant story of an unlikely friendship, which unfolds as a revelation on how we hold on to - and pass on - what matters most. Everyone knows the two Sophies are best friends. One is in elementary school, and one is . . . well . . . in a little trouble of late. She's elderly, sure, but she's always been on her game, the best friend any girl struggling to fit in could ever have. The Sophies drink tea, have strong opinions about pretty much everything, and love each other dearly. Now it seems the elder Sophie is having memory problems, burning teakettles, and forgetting just about everything. It looks like her son is going to come and get her and steal her away forever. Young Sophie isn't having that. Not one bit. So she sets out to help elder Sophie's memory, with the aid of her neighborhood friends Ralphie and Oliver. But when she opens the floodgates of elder Sophie's memories, she winds up listening to stories that will illustrate just how much there is to know about her dear friend, stories of war, hunger, cruelty, and ultimately love.
