Two KDP freebies (should be free at all Amazons, am only linking main):
, a crime thriller by Roger Smith. Paperback out from Profile (no date given in the Amazon listing, but author has several books out from Henry Holt and I've previously included him in KDP listings). Blurb quotes recent newspaper praise for this particular novel.
The Dead Room
legal/psychological thriller by Robert Ellis. Originally out from Kensington's Pinnacle imprint in 2002.
Non-KDP freebies available to all via Smashwords (may or may not be price-matched elsewhere; are definitely not via Amazon in Canada, who no longer price-match non-KDP freebies for us):
Murder Passes the Buck
& Dolled Up For Murder
by Deb Baker in her Gertie Johnson & Gretchen Birch mystery series, respectively, originally out from Llewellyn's Midnight Ink imprint and Berkley, both in 2006.
A Dyeing Shame
by Elizabeth Spann Craig. Out from "Palmland" in 2006, but is 1st in her Myrtle Clover mystery series which has been picked up by Midnight Ink. Author also writes as Riley Adams for Penguin & Berkley, according to her bio.
iTunes freebies available to some (may or may not be price-matched in certain regions; are definitely not via Amazon in Canada):
by Colin Falconer. 1st in some sort of multi-generational Asian drug-running thriller series, IIRC. Originally out from Stodder & Houghton in 1994, and a previous KDP post listing inclusion.
Bonus historical freebie from Falconer (may be self-pub): Jerusalem
, some sort of multi-book epic saga about pre-WWII Palestine.
Created the Destroyer
by Warren Murphy & Richard Sapir. Action thriller series w/political satire, according to the blurb. The Destroyer series is very long-running, and much of it used to be available quite cheaply via Fictionwise during coupon sales via the e-reads reprints (rights seem to be in transition, e-reads seem to only have #51 and up now
). This one is 1st in the series, reprint handled by Gere Donovan (who also used to run the online e-book checkout for Poisoned Pen Press and Dana Stabenow) and the earliest paperback listing I can find for it is from Pinnacle in 1971.
ETA: Just because I feel like it: The Village,
a KDP self-pub nature disaster thriller novella by Canadian mystery writer Mobashar Qureshi, whom I've previously given the title feature spot in KDP listings for his Mercury Press-published novels which received some acclaim from Quill & Quire magazine, which is like Canada's version of Publishers Weekly. He also has some Smashwords freebie shorts
