Angela doesn't like her Aunt or cousins but living them with has to better than the series of children's homes she's had to put up with. She's, therefore, determined to bite her tongue and behave like an angel when she's invited to join their family holiday in France. Her cousins don't make this easy but Angela soon has bigger concerns to occupy her mind – namely the mysterious boy on the other side of the Mirror Door and the fact that he appears to be dying, alone and uncared for in 1898.
