Open Road are having a "Brooklyn Grit" sale with ten mysteries at $1.99, for an unknown amount of time. Usually I get emails about their sales, but just stumbled on this one, so don't know how long it is good for. Often their sales seem to be for the month, but unless someone else can confirm, don't count on it!
The ten titles are:
Gabriel Cohen:
Red Hook
Peter Blauner:
Slow Motion Riot
Stanley Ellin:
The Dark Fantastic
Lawrence Block:
The Specialists
Joseph Koenig:
Little Odessa
Lawrence Sanders:
The First Deadly Sin
Stuart Palmer:
The Green Ace
Don Winslow:
A Long Walk up the Waterslide
Stephen Solomita:
Force of Nature
Donald E. Westlake:
A Jade in Aries
The link to the sale page at Open Road Media is:
http://www.openroadmedia.com/brooklyngrit?
And from that page you can go to any of the various retailers by clicking on the "Buy the Ebook" button and then choosing from the drop-down menu.
I checked all of these at Kobo US, and they are all $1.99 (and presumably couponable) there. Also all $1.99 at Amazon US.
Many of these have been on sale before, but a couple were new to me.
