Karin Slaughter (website) is the author of two popular mystery series, Will Trent and (my favorite) Grant County series. While the two mystery series are distinct from each other, in 2009 the author linked them through the book Undone (Genesis in the UK), so right now we have 2 main series and a third one unofficially called the Genesis series.
I’ve actually read her books in order right from the start. I’ve been introduced to Karin Slaughter through Blindsighted in 2001, her very first novel. It is also the first in the Grant County series, a forensic mystery series set in Georgia focusing on three main characters: Sara Linton who is the local pediatrician and also part time coroner, her ex and current husband Jeffrey Tolliver and another strange character named Lena Adams, who is working for Tolliver. The series has 6 books with the last one written in 2007.
The second series, Will Trent, takes place in Atlanta alternating with Georgia (some books in the series are also called the Georgia series) and has as main characters the FBI agent Will Trent, Faith Mitchell who is his partner, and Angie Polaski. Later on through the connecting novels, Sara Linton the main protagonist of the Grant County series also joins forces with them in a few following books including Undone, Broken, Fallen, Snatched and Criminal.
Her latest novel published in 2013 is called Unseen and it is the 7th in the Will Trent series (well technically it’s the 9th one as there are two short novellas part of the series before this).
In addition she has written several novels and short stories, all as standalone books.
