About this list
3 of them still run, while 3 have finished. None has a dated next book yet, although that can change at any time. Finished series need no catching up, but a running one gains a new book from time to time.
Romance is the biggest shelf here, with 2 series. Children's & Middle Grade has 1 and Mystery & Crime has 1. Since each shelf has its own page, you can narrow the list by genre.
The three biggest are Under Suspicion (8), Ultramarines (7) and The Underland Chronicles (5). The shortest runs have only 3 books, such as The Underdogs. Both kinds get the same checks, because a short series can still hide a tricky order.
Brad Lee is one of 6 authors in this list. In all, 6 authors are behind these series. Since each name links to an author page, you can follow a writer to their other work.

A series can have more than one order. The publication order follows the release dates, while the chronological order follows the story. Where the two differ, the page shows both and says which one we would pick first.
Each series page shows the publication order, any chronological order and our recommended place to start. We also note where a novella or companion book can safely wait. Because the list runs A to Z, the letter bar takes you to any other part of the alphabet. If you would rather search, the search box finds any series by name, and the genre shelves group series by theme.
