Thomas Archibald Barron was born on March 26th, 1952, in Boston, America. He writes many books for young children. Where is Grandpa? is one of them. 

Grandpa is cool and fun. His grandson likes to be with him. They play in so many interesting places—at the treehouse, at the waterfall（瀑布） and at the door. Both of them like going on new and fun adventures（冒险活动） . The boy and his grandpa are like best friends. The boy is so lucky to have such a great grandpa.

Where is my grandpa now? The young boy keeps thinking of this on the day his grandpa dies. 

One day the boy asks his parents, "Where is my grandpa?" They tell him that he is in all of their memories（记忆）. Then the boy thinks a lot. He learns to be strong from some things in life.
