I suspect I've read this before. But I couldn't resist buying this from the second hand bookstore today. RM2 would you believe it? A hauntingly touching book about an orphan who doesn't interact well with other children. Anna, whose granny died just before this story starts, is sent away to the seaside to recuperate from asthma. She befriends Marnie and together they have loads of adventures together. As the story unfolds, you begin to suspect Marnie might not be totally alive by the sudden emergence and the timing. She always seems to be waiting a long time for Anna to appear to have fun. Anna doesn't seem to think so. For her, the days pass and when night comes, she seeks Marnie out.
