Rachel, around what year did you read this book? A range of years is fine.

Who does he work for? What's the location? Is there romance?

Thanks. I added a few details to the header/topic title. You can update it by clicking the small "edit" link after the header. This only works on the full Desktop website - not the Mobile website or app. (On the Mobile website, click the "Desktop version" link at the bottom of the page.)

It can be moved now to solved somehow right?

Glad you found it
