I read more in a week than most people do in a year. My current reading project is the four book fantasy series Ancient Dreams, which I started earlier today (2/19) and am a quarter of the way through the third book. As I went through them I also realized that I'd read the series when it was originally published a couple years ago, so more like an inadvertent re-reading.
I'm not sure what's next on the list, I often see what's new in Kindle Unlimited and try things that catch my fancy there. If it's something that suggests being "book X of a series" I go back to find the first book and start from there.
