I'm in my 70s and bought this book when I was a child. Even then it was very old. Could be from the late 1800s or very early 1900s. I still have the book and recall crying buckets every time I read it (yes, I read it several times). It's very old-fashioned and religious in a way that is quaint these days. It's a sad story about 2 children living on the street as their mother is a lone parent and alcoholic. The little boy cares for his baby sister as his mother isn't capable. One day his drunken mother loses the baby who is now a toddler. She wanders off and is lost. The story involves the boy's search for his baby sister. This story takes place in that era in London where people were becoming aware that disadvantaged children needed help, and that childhood was actually a vulnerable time, where children needed nurturing in order to survive. Charles Dickens was an author of this time who highlighted the plight of disadvantaged children (remember Oliver Twist). This book isn't up to the standard of Dickens of course, but if you need a good cry it's a great place to start. A tragic tale with a happy ending - thank goodness, as there's too much tragedy throughout this tortuous tale.
