Who are the people who wrote book bittersweet sixteen and what other books have they written?

"Sweet Sixteen" is a common theme in literature, but there's no single book titled "Bittersweet Sixteen." There are many books that explore the complexities of turning sixteen, often with a bittersweet tone.

To help you find the book you're looking for, could you please provide me with more details? For example:

* Do you remember any specific characters or plot points?

* Do you remember the author's name?

* Is there a specific genre you're looking for (e.g., contemporary, historical fiction, etc.)?

Once I have more information, I can help you identify the book you're thinking of and tell you about the author's other works.
