The Chatswood family tree has many branches--and even more secrets. It's the summer of 1914 in England, and Beth Etheridge, great-granddaughter of the original Elizabeth Chatswood, can't wait for her twelfth birthday to arrive. That's when she'll receive her family's heirloom "Elizabeth" necklace: one half of a heart encrusted with beautiful sapphires. (The companion necklace, encrusted with rubies, will be given to Beth's American cousin and pen pal, Kate, later in the series.) But when family from France visits Chatswood Manor for the occasion and another family heirloom goes missing, Beth finds herself on a quest to clear the name of her lady's maid and friend, Shannon. Her search for answers leads her to a hidden diary with clues to a much larger family mystery that dates back generations. What secrets are hidden away in Chatswood Manor?
