A gamebook you should order if you don't have it. Do add this to your collection!
Age: Adult (contains a little swearing, plenty of violence, some ritual sacrifice, a touch of sexual harassment, a fair amount of discrimination against mythical creatures and a highly illicit relationship with a water cooler).
Story: You are an office temp who has fallen on hard times. Desperate for any work you can get, you take a data entry job at Firetop Mountain Plc. You must navigate the dank corridors, placate your co-workers and do as little work as possible while still getting paid...
...until you discover you're being bled dry to power a mystic portal to a fantasy realm. Lost in the basement with an IT troll and the tea lady, you must fight your way through the building in an epic quest for survival, revenge and someone to sign your timesheet.
I heard about this last year and saw some good reviews for it so I bought a second-hand copy in good faith. Started reading it and by god it was absolutely abysmal, like something a couple of 12 year olds made up in their lunch hour. Painfully embarrassing to read, I can't remember how far I got but I wouldn't recommend anyone ever buy this, I hardly paid anything for it and still felt ripped off, it was back on ebay again within the week.
