The Last Widow by Karin Slaughter

She writes a series with the characters Sara Linton and Will Trent, and this is # 9 in that series. A scientist from the Centre for Disease Control is kidnapped and then a month later there’s a couple of massive explosions in downtown Atlanta. Our heroes rush to the scene, and straight into the heart of a deadly conspiracy which is putting thousands of innocent lives at risk. Great stuff! Slaughter (so aptly named) does these books really well.
