Karin Slaughter writes. It doesn't matter - stand alones or series. Her newest book, The Silent Wife is the tenth entry in the Will Trent series.
(Side note - this could absolutely be read as a stand alone, but you're missing out on some great reads if you've not read the previous books)
Will is an agent with the GBI. While investigating a riot at the prison, one inmate demands to talk to an agent. He insists that he is innocent, the killer is still out there and that he was railroaded by Sheriff Jeffrey Tolliver. Tolliver is the now deceased husband of Will's girlfriend (and coroner) Sara Linton. Whew, that is just the bare bones - there is so much more to this plot - did I forget to mention the serial killer?
Long time characters return - Will's partner Faith, Will's boss Amanda and....oh yes, the character I've loved to hate - Lena. Lena is a detective now, but her background, her actions and her time working under Tolliver (and now) are sketchy. And....there are chapters from the past through Jeffrey's point of view.
Slaughter's writing is amazing, her plotting is stellar and the characters are ones I've come to know and care about. (most of them.) The relationship between Will and Sara is also explored in The Silent Wife. Will is a wounded soul and Sara is carrying her own baggage. No sappy stuff here - but an exploration that suits the characters. (And I admit it - I'm a little infatuated with Will myself.)
An absolutely brilliant read! And - there's more to come - I can't wait for the next in this series!
