I remember reading a great book called Dolphin Island as a nipper at school (I was around 10-11 I think). Idly googling on a rainy day, it turns out it was by Arthur C. Clarke. Neat. I read it all really quickly and maybe even shed a tear at the end I enjoyed it so much.
But.... there was a different book I remember reading part (maybe all) of. I only remember vague details which I'm going to post up and see if anyone recognises it; like the name-that-tune style topics.
It was sci-fi lite sort of style. Like an adventure. Space travel.
The main characters were teens.
The key detail:
They had a spaceship, made from (possibly) a hollowed out meteor. It was like a large snail-shell in it's design, like a large-ish spiral laid flat. The ship was quite fragile and crappy, they couldn't fight with it, only run away from trouble. I remember bits set in a kind of junk yard, finding bits for repair etc.
There were a few pictures in the book, but simple pen-drawing style.
Does this ring any bells with anyone?
