A book finished over Christmas / New Year from the "been lurking around here for quite a long time now" stacks.
From the Blurb:
Ten years ago Andrea Hayes was the IRA's most brilliant bombmaker. Then, sickened by an incident that went horrifyingly wrong, she gave it allup. Now she lives a safe suburban life, her true identity hidden from even her husband and daughter Katie. But when Katie is kidnapped, Andrea realizes that her past, chillingly, has come back to haunt her.
