How do you pretend everything is fine when those that you love are in danger? If people you once trusted are now deemed a threat?

After winning the National STEM Championships, Kensy, Max and a team of students from Central London Free School are ready to compete for the international trophy in Singapore. But when Granny Cordelia is poisoned, the twins no longer feel like celebrating.

They still have a duty to their team though, and everyone seems to think they’ll be safe in a country halfway around the world. It turns out that Singapore is rife with mysteries. Soon Kensy and Max have uncovered a much larger case than anyone counted on. And this time, it’s personal.

Author Biography

Jacqueline Harvey worked in schools for many years but has had a passion for storytelling since she was a child.

She is the author of the popular Alice-Miranda, Clementine Rose, Kensy and Max and Willa and Woof series, which have sold almost two million copies in Australia alone. In 2022, she released a picture book, That Cat, illustrated by one of her former students, Kate Isobel Scott. Jacqueline’s books have received numerous shortlistings and awards while her picture book, The Sound of the Sea, was a CBCA Honour Book.

Jacqueline speaks to thousands of young people at schools and festivals around the world, and says the characters in her books are often made up of the best bits of children she’s met over the years. While she is not a twin, like Kensy and Max she does have excellent powers of observation and has always thought she’d make a great spy.

Jacqueline lives between Sydney, Australia, and Queenstown, New Zealand, and is currently working on more Willa and Woof adventures, several picture book projects and an exciting new middle-grade story.
