I just wanted to plug the current offer over at Whole Story Audio Books for books narrated by Maggie Mash. I've been a fan of her work since I listened to Phoenix by John Connor. I'm currently playing catch-up with Stella Rimington's books as her fourth is out soon from Quercus - I've listened to Secret Asset and have almost finished Illegal Action - another series that Maggie Mash narrates. (You can listen to a sample of her narration at the site.)
Currently there's 20% off her titles. See here for the whole list.
