Yes one of these threads.
A book I read when in primary school so very early 90s, though obviously no clue of publication date. Got it from the library several times.
It was about a group of people / families on a space ship travelling to colonise a new planet. Possibly as an emergency as earth had become uninhabitable. They were all allowed to bring 1 book only and the main character (a child, a girl I think) had brought a blank notebook and every one laughed at her.
When they arrived they struggled to cut trees to build houses as they were so hard. The grass was pink. The settlement was a success and basically she wrote it's history in her blank book and everyone was grateful she brought it.
Anyone have ideas?!
