Maybe a whale

After Grandpa dies, a girl and her mother take the trip he had planned for her, kayaking along the Pacific west coast to look for the whales that he loved. The trip will do them good, Mom says, but the girl isn't sure. How can that be true when Grandpa isn't there? And how will they find a whale in all that water, anyway? There is so much to see as they paddle through white-tipped waves and calm coves: glowing moon jellies, fluttering anemones and slippery seals. All the while, the girl watches for whales. Could one be swimming beneath their kayak or along the shore of their camp? Are the whales even there? Finally, in the dark of night, they hear them -- pushhhhhhhh, pushhhhhhh -- humpbacks breathing in the bay.
