There’s an anonymously written ebook circulating called 100 Facts Every Atheist Teen Must Know.
There’s some decent stuff in it. Though it gives the same amount of space to “God” as it does “Alcohol” (but maybe that’s inevitable in a document like this). It also includes a couple random topics (like “Banking” and “Lindy Hop”) without making any direct connection to atheism.
Anyway, it’s free and you can check it out for yourself, so I’ll stop complaining.
