Two omnibuses in Gail Bowen's Joanne Kilbourn series have gone on sale in the US at Kindle and Kobo US - the first one is a pretty good deal, and the second one is quite a good deal, assuming you don't need any of them. I'm quite fond of this series, so sadly, I already have a lot of these.
The Joanne Kilbourn Mysteries 3-Book Bundle Volume 2 contains:
A Colder Kind of Death (which won the 1995 Arthur Ellis Award for Best Novel),
A Killing Spring, and
Verdict in Blood. It is $7.99.
