Although I don't specialize in metaphysics, I'm perennially interested in it and like to keep on it as much as I can. Anyway, I've read several articles on modality recently that really piqued my interest, and which and figured it couldn't hurt to share them. The first article I came across is Jonathan Jacobs', "A Powers Theory of Modality: or, How I Learned to Stop Worring and Reject Possible Worlds." Then I read Barbara Vetter's recent paper in Analysis, "Recent Work: Modality without Possible Worlds."
I think (naively, perhaps) that what Vetter calls the "new actualist" approach to modality -- understanding modality in terms of essences or dispositions rather than possible worlds -- may be a real agenda-setting development. So much philosophical argument over the past several decades seems to have been predicated upon what Vetter and Jacobs call a Humean/Lewisean metaphysical picture: a picture where objects and properties bear no necessary connections. What if, as the new actualists suggest, this Humean/Lewisean picture is false? Anyway, I think the stuff is interesting and well worth reading, if only as a stimulating counterpoint to a now orthodox way of thinking.
