Just an avid reader. Mostly SF/Fantasy, some hobbies, paranormal, urban fantasy and lighter, fluffier things.
Not new (been around long time), but in case any SF/F fans overlooked, publisher Baen offers The Baen Free Library -- a digital library of the science fiction and fantasy publishing house Baen Books where e-books can be downloaded free in a number of formats.
Often it's the first book in an ongoing or a backlist series.
(They also have for sale eARCs of brand spanking new books well before available at retailers at http://www.baen.com/baenebooks#eARC )
Links to the download the ones I featured (they offer many more):
