Liars is an action-packed thriller series about a kid who invents a lie detector app, accidentally exposing everyone’s darkest secrets and making him the target of a criminal mastermind known only as Viper. The series is perfect for reluctant (and voracious!) readers aged 10+.

“Jack Heath is the Australian master of the YA thriller, and (The Truth App) is another non-stop action-adventure ride, from the car crash on the opening page to the tense finale in a remote warehouse… recommended for upper primary and lower secondary fans of techno-thrillers packed with tension and plot twists.” -Heath Graham, Books+Publishing
