Take my word for it, man: don't try and read them now. I made the mistake of dusting off a few of them from the massive collection I've got from back in the day. And wow...they aren't all that good. I think I might have gotten them solely based on the cover anyway.
I remember I had Say Cheese and Die and Lets get Invisible. I had another one where you chose your destiny. I forget what it was called.
You know what's really funny? Back then when I was a kid, I'd pick one up and be like "Awww, I have to read ALL of this?" These days I'm writing 200 page novels of my own, lol. Wow.
We had these but another series too called 'Point Horror' which was basically a label used to bring over a ton of Y.A. horror books from the U.S. Fantastic memories.
I had a bunch of these.
