Cassie Hevans and A Christmas Carol (in July)

Book excerpt: *** A Christmas Carol but not the one we know *** Until she discovers a rare first edition of A Christmas Carol in an ancient Glastonbury bookshop, Cassandra Hevans is almost sure she's put her peculiar childhood behind her. But this Christmas Carol isn't the one everyone should remember, and the book keeps on changing. Mystified, Cassie returns to the bookshop, only to find herself transported into another world, one all too horribly like the Carol she's reading. Could it be real, or is her childhood illness returning? Who is Naomi, the young woman who guesses far too much? Why is Cassandra's real world changing too? And why can't her best friends sense it? Cassie needs to find the answers soon, because time is running out for the Carol and for the real, unwritten world, and unless she can heal them both they will be darkly twisted forever.
