Don't Let Me Go by Susan Lewis

Charlotte Nickolls can hardly believe it, but she seems she's landed in paradise.  Living in a cottage on the beautiful Bay of Island, surrounded by the splendor or New Zealand, Charlotte reveals her new life.  She and her nearly 4 yr old daughter Chloe have started over with the help of Charlotte's birth mother who has recently reentered her life after a 26 yr absence.  But horrors of the past-both recent and long buried-are never far from Charlotte's mind.  And then their idyll is suddenly shattered as a series of events is set in motion that Charlotte can neither control nor comprehend.
