I need major help... I am looking for one of V.C. Andrews sách that involves a forbidden love, a shipwreck, girl gets amnesia and her grandmother takes her in and knows about the girls past but doesn't tell her about it. The girl starts to remember things and starts putting pieces together. That's all I have. Does anyone know this book?
