Initially I wouldn't recommend it, but I've been coming around to the idea that you should start with the first three Horus Heresy novels, because the event is so foundational to the rest of 40K.
I by no means recommend someone then go on to the other 60 books in the series, but Horus Rising, False Gods, and Galaxy In Flames provide so much background and context to what comes after.
