An anthology of romance novels, including (in addition to Lucy Walker's novel), Bride of Pendorric by Victoria Holt and The Heir of Garlands by Hebe Elsna.
'Two girls are among the twelve-strong team that sets out on a botanical expedition to the Australian outback. Myree is outwardly the more striking - a qualified botanist, brilliant and dazzlingly beautiful. She sets out to oversadow Kim, who is pretty but shy and much younger.
'For a time it looks as though she will succeed. Then both girls fall for Dr John Andrews, the handsome leader of the expedition. And Kim shows that she is not so shy and naive after all.'
