Slightly Invisible (Charlie and Lola)

Charlie learns that visibility is relative — but Lola’s quick-wittedness is crystal clear — in this 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 milk — it turns out that the strange and tricky creatures have met their match in one very resourceful, inventive little sister.
