Welcome to the wonderful world of blog giveaways. So yes, it's not only websites where you can win free books, there are a whole lot of blogs out there where you can do the same.
I Am A Reader, Not A Writer is a blog that hosts a whole lot of fabulous Giveaway Hops throughout the year. The next one is the Follower Love Giveaway Hop which takes place from February 8th through February 13th. Over 200 blogs have signed up to host a book related giveaway and they are all linked up together so you can easily hop from one giveaway to another. While I will only participate in this one as someone who really wants to win *ahem* I intend to sign up for one or more of these giveaway later this year too.
As for trying to win - this is probably the first time that I'm actually glad that not each and every single giveaway in this hop is international (because a lot of giveaways out there are usually only for US or US/Canada). The good thing, of course, is that a lot are open worldwide. Otherwise a whole lot of book-crazy chicks like me would be devastated.
So I did enter a couple already, slowly working myself through the list, but not nearly done yet. It'll probably take me until the last day to enter them all (even if I can only do the international ones), because I usually remain at a blog a little time and browse around there too. You see, that hop isn't just great to win free books or giftcards for Amazon or the Book Depository, it's also a fantastic way to find interesting book blogs out there.
And while the list of blogs I'm following is constantly getting longer and my fingers are crossed so I may win *pretty please* why don't you head on over to I Am A Reader, Not A Writer yourself to join in the Follower Love Giveaway Hop.
