Yes, afaik there are only two though, Divine Divinity and Beyond Divinity, I highly recommend them both, I'm not sure why Divinity Two is so called, as I figure it to be the third in the series.
BD on its release in some region/s was accompanied by a novel written by Rhianna Pratchett, who also contributed to the script of D2.
Anyway, hope you manage to get a copy of either and enjoy them
