Beyond Corny Groń books available

Hi folks!

As we are proceeding with shipping of KS-pledged books, Szymon set up a store for those who may want to buy Beyond Corny Groń book. So, if you want to grab your copy (or you feel the piece you've got from KS is not enough!), or you want to have solo Corny Groń as well, you can take a look at https://nerdsirens.pl/ and treat yourself :)
