Sunday Times - The business section is like an "FT Lite" with a summary of recent business news, short articles so easy to read over a few days. Obviously text books but not knowing which ones she has it's difficult to add, but you could suggest some autobiographies that are worth reading - she can always add and attribute the odd quote to an assignment. Branson and Sugar's spring to mind. Both are fairly easy reading.
If there's a particular area that she's interested in, most have monthly or weekly e newsletters or magazines.
Sorry if this is no help but I'm rewatching Man City v Stoke, and it's duller on replay than it was in real life.
