A Ghost Tale For Christmas Time by Mary Pope Osborne illustrated by Sal Murdocca*

My second grader read this book to himself.
Jack and Annie travel back in time to London during the Industrial Revolution.  Here they meet a disheartened Charles Dickens and help revive his creativity and love for life.
My son said he liked the magic violin and how Jack and Annie help Charles Dickens so he can write "the Scrooge story".
*Highly recommend series.
Pair with any version of A Christmas Carol and Ms. Osborne's Fact Tracker-Rags and Riches-Kids in the Time of Charles Dickens.
