Do you like creepy and slightly scary books that have ghost in them? Well this is one that I think you might like It's bone chilling and spine tickling somewhat at the same time.
Two of the main characters I'd say are Annie and Elsie. The conflict is that a bad case of influenza was spreading, Elsie got sick and died, Annie knocked into Elsie's tombstone and then "woke up" from the died.
I like One For Sorrow because it was very thrilling and there was a happy ending, but before it ends there was a sad and happy moment for Annie and Elsie. One character I found lovable was Mrs. Jameson , she is very nice to Annie and talks about books with Annie sometimes.
That is I like the book and why I think others might like it, too.
