Charlie learns that visibility is relative - but Lola’s quick-wittedness is crystal clear - in this absolutely new picture book from Lauren Child.

Charlie and his friend Marv have invented an invisibility potion to help them find strange and tricky creatures, which they would prefer to do without Charlie’s little sister, Lola, bothering and interrupting. But when Lola enlists a bit of help from her invisible friend, Soren Lorensen - not to mention a tea set, a rabbit, a stroller, and of course one or three glasses of pink mil k- it turns out that the strange and tricky creatures have met their match in one very resourceful, inventive little sister.

How do you catch a thief who isn’t there? Ruby discovers the perils of throwing caution to the wind as she embarks on her fourth adventure.

Ruby Redfort has a lot of reasons to feel confident. Undercover agent, code cracker, thirteen-year-old genius — she’s one fearless kid, buster. Unmasking an evil villain? Done. Honing her parkour skills by climbing skyscrapers and leaping across roofs? All in a day’s work. Heeding the warning signs? Well, not so much. When a ghostly foe begins stealing from the highest buildings in Twinford, Ruby Redfort is ready to defy death one more time to capture the bandit. But fearlessness can lead to taking risks, which can land a person in very serious trouble. While Ruby may think she’s invincible, there’s truth to the saying that recklessness always comes before a fall.
