I read this book as a child in the mid-90s. It might have been published earlier. Unfortunately I remember nothing, except for the cover, which showed two girls (age ~8) standing in a stormy ocean, wearing Medieval-ish dresses. One of them is collapsed and the other is supporting her.
Was this about a group of young girls/friends on an island, the name hope rings a bell, she was a twin to Hannah? Maybe?
