Today I got this tweet: https://mobile.twitter.com/giantsqui...21629486268416
"@Trombolii love the sound of DARCY DARKLING and what I read on your blog! would love to read more, too! http://t.co/zkoDTV2tXi" From Giant Squid Books. (Darcy Darkling being the MG I'm curently querying. I have the query and first page on my blog) The website doesn't give much information at all. One red flag for me is that their number 1 reason why you should submit to them is "It's free!!!"
No idea who's running this or what kind of background they have (I think they're authors)
Not a lot to recommend them.
