Heirloom

I don't know if books count as heirlooms in the strictest sense, as this is my personal copy bought for my birthday, I can't remember when. Probably I was about 12. I don't remember if it was Granny or Meg who got it for me, as they certainly conspired over it. They'd clearly been waiting for ages, assessing whether I was old enough to appreciate it. They were definitely more excited than me, until I read it.

Possibly you've never even heard of it, but if you like sci-fi-comedy-prison-break stories, it's just the thing for you.

Altogether now: "Asta Zangasta's a dirty old geezer, got fleas on his chest and sores on his beezer"
