Now Available: Pretty Little Wife by Darby Kane (AKA HelenKay Dimon)

December 29, 2020

It’s here! Pretty Little Wife the twisty thriller of domestic suspense you’ve been hearing about for months is finally in reader hands. In a STARRED REVIEW, Booklist called it “A page-turner built on skillfully layered plotting and an intriguing protagonist.”

But who is Darby Kane? Darby is HelenKay! But while you can count on romance with a happy ending from HelenKay Dimon, a Darby Kane book is a very different kind of book, hence the different name. Pretty Little Wife is much darker, and romance is not the main theme. This is a thriller, through and through. It starts with a wife, unraveling secrets, and a dead husband. The end is not guaranteed, and getting there is a fast-paced ride.

HelenKay is totally thrilled her thriller is out! Find her on Twitter celebrating the release. And check out Pretty Little Wife for the answer to the question: Shouldn’t a dead husband stay dead? Read an excerpt then buy yours in print, ebook, or audio.
