For a limited time
Fires of War is available free for the Kindle via Amazon's UK site.
Fires is the third book in the First Team series, which features Bob "Ferg" Ferguson as a free-wheeling, smooth-talking CIA officer who works with a group of special operators and is backed up by a Special Forces unit.
You can download the book here. The free offer expires Monday.
(I know it's book three, but you can certainly read them in whatever order you want.)
