I've just finished Jan Siegel's Prospero's Children, a more modern and slightly older take on the kind of ideas and themes Susan Cooper used in her The Dark is Rising series. Well-written, and with a great evocation of Atlantis, but a book of very separate halves which made it feel disjointed, and the 16-year-old MC and her 12-year-old brother came across as both being several years older (which might not have been a bad thing).
Before that, I read Warlord of the Air and The Land Leviathan, the first two of Michael Moorcock's Bastable books. A definite steampunk feel -- which, given they were written in the 1970s, makes them very early examples, maybe the first? -- and they were initially enjoyable, and engagingly written. But Moorcock doesn't seem much interested in shaping stories, and I wouldn't say they were very satisfying in the end.
