Children of Eve by Deirdre Purcell

Eve Moraghan broke one of the great taboos when she abandoned her children as toddlers. Now adults, Arabella, Willow and Rowan have heard nothing of their mother since the day she walked out the door, headed no one knows where. Why she went, they just don't know. But now, it seems, they're about to find out. Their mother's been in an accident, and she's sent word that she wants to see her children. The first reaction is to tell her to forget it. She gave up on them - why should they jump when she says so? And yet somehow they each find themselves on that plane, making the journey that will tell them what their past was all about - and open new doors into the future.
