This is another good historical(ish) thriller that follows the Courtney family, this time during the 70s where young Isabella Courtney is tricked into dishing out trade secrets and detailed information on weapons and satellite information to some not so pleasant characters. Against this backstory, we also follow the other members of the Courtney family as they go about their lives before uncovering Isabella's secret. I did find the main story a little unlikely, even for one as ditzy as Isabella, but this aside, it was an enjoyable read with a dramatic and entertaining conclusion.
