I think everyone who loves books has an inaugural series in their background that opened their eyes to a wider world of reading possibilities. For me, that series was Lloyd Alexander's Chronicles of Prydain. If you want to read a quick history of Lloyd Alexander, check out this post. It's nicely done.
I've had this series on my re-read list for a long time now. At one point, I owned all five books in the series; somewhere between the age of 10 (when the editions I own were published and presumably about when I first read them) and 40 (my current age), 2 of those books were lost. I still have books 3, 4, 5, and remedied the missing novels with a couple of quick purchases from Amazon's used book section.
I don't know if I'll post formal reviews of each book; I've slowed my reviewing so I can focus on other things. But I might post some thoughts once I'm done with the series. The difficult thing about re-reading such a formative work is that my expectations are high. As a 10 year old, I'm sure I tore through them. I was always interested in fantasy; a series of this magnitude in an easily digestible form probably kept me up until the early hours of the morning. But will the Prydain Chronicles hold up to the critical eye of the 40 year old curmudgeon I've become? I'll let you know.
