If you're interested in the lore of the plane, I enjoyed the Llorwyn/Shadowmoor cycle books and recommend them, but they are a bit of a mixed bag. I think the first one is the best, a great intro that segues into a classic fantasy adventure of strangers coming together with teasers of the larger plot. The second meanders a lot with a bunch of characters just wandering around in the forest and monologuing to themselves. The third must have run into time issues as it's a collection of short stories by various authors that range from bad to amazing. It's great at building out the lore of Shadowmoor (especially the cinders) and can be read on its own if you want as it's very light on connections to the rest of the books. The last book wraps up the story from the first two books pretty well, though I think some of the parts were a little under baked.
