Book description
Alice Butler has been receiving some odd messages - all anonymous, all
written in code. Are they from someone at PopCo, the profit-hungry
corporation she works for? Or from Alice's long lost father? Or has
someone else been on her trail? The solution, she is sure, will involve
the code-breaking skills she learned from her grandparents and the key
she's been wearing round her neck since she was ten. PopCo is a grown-up
adventure of family secrets, puzzles, big business and the power of
numbers.
