Shadowland (Main/
UK), the third title in the Zoe Lawrence Mystery series by Pam Leonard, is free in the Kindle store, courtesy of publisher North Star Press of St. Cloud. The paper edition is still to be released (coming in September), so I suspect the Kindle edition is using what the publisher calls "guided self-publishing", which they offer to select authors in order to guide them thru getting a professional looking book published (and which, presumably, doesn't include quite the same level of editing and proofing you might expect from a larger publisher).
Book Description
With Shadowland, Pam Leonard shatters the myth of Minnesota nice. In scene after powerful scene, Leonard explores the dark heart of homelessness and sex trafficking in the Twin Cities. The result is a twisted and harrowing journey down unexpected mean streets and dangerous alleyways. It’s an experience you won’t want to miss.
