In the war-ravaged England of 1940, Charlotte Bromley is sure of only
one thing: Kitty McLaughlin is her best friend in the whole world. But
when Charlotte's scientist father makes an astonishing discovery that
the Germans will covet for themselves, Charlotte is faced with an
impossible choice between danger and safety. Should she remain with her
friend or journey to another time and place? Her split-second decision
has huge consequences, and when she finds herself alone in the world,
unsure of Kitty's fate, she knows that somehow, some way, she must find
her way back to her friend. Written in the spirit of classic time-travel
tales, this book is an imaginative and heartfelt tribute to the
unbreakable ties of friendship.
