I am so far behind, that I haven't had the chance to wander around all of the fun contests that I usually haunt...but there are a few that I make it a point of keeping up with...
The Romance Reviews Anniversary Party continues until the end of the month. I love playing the hangman game in particular!
Lisa Renee Jones always has contests at her blog at this link
and she runs others such as this one for a signed special edition at this link
The I Smell Sheep blog always has fun reviews and great giveaways (and I love the way their newsletters tempt you to click on the feature with 'what the flock'...) and they're having a big March giveaway.
Reviews by Crystal frequently has fun giveaways to go with the great reviews
Those of you who use other forms of social media (FB/Pinterest/Twitter) can enter for a steampunk book in a great series by Bec McMaster at the Coffee Time Romance Steampunk area! While you're there, wander around, there are lots of great features. I had been locked out of there for a while, but it seems that my computer is finally letting me back in without dire warnings, lol.
There are lots more contests out there...feel free to share others in the comments!
