This is based on the list created by members of the SOS: Series Overload of Series group in this thread.

"Urban Fantasy stories involve mystery and action. The characters are mostly concerned with achieving a goal (saving the world, themselves, people they love). There are often romantic subplots, but they aren’t the main focus of the book.

In UF, you have the same main character(s) across all books in the series, they are usually narrated in first person and set in a city or urban setting."

Please, make sure you only add the first book of each series to this list.
