Lauren Child talks about Ruby Redfort: code cracker, secret agent, school girl. Every smart kid’s smart kid, Ruby first appeared in Lauren Child’s best-selling Clarice Bean novels. Now, as befits a 13 year-old secret agent, she has her own series. Super smart and super cool, Ruby’s latest adventure, Take Your Last Breath, involves close encounters with sharks, cut-throat pirates and a giant tentacled sea monster. Luckily the ocean’s no problem as long as you can hold your breath for more than 61 seconds. Can Ruby do it?
