Great African Reads discussion

I read The Running Man a while back. I think it's just the UK version of This Voice in My Heart, but they're listed as separate books, and I can't find anything to confirm that they're the same thing. I saw that this group read This Voice in My Heart as part of the Tour d'Afrique (granted, a while ago), so I'm hoping somebody knows whether they are different editions of the same book -- if they are, I'd like to combine them; if not, well, then I want to read This Voice in My Heart! Any thoughts? Thanks in advance.
