The Shampoo Effect: A witty and irresistible new novel for fans of The Wedding People and Blue Sisters

When writer Caroline Lash arrives in Greenhead, she falls immediately for its scenic beaches and New England charm – and even harder for Van Whittaker, a gorgeous, fleece-wearing, litter-collecting, kayak enthusiast.

She meets his friends: Augusta, old money and uptight; Fran, drowning in everyone else’s problems whilst keeping two kids (and an inebriated husband) afloat; and Bailey, who is sexy, confident . . . and inconveniently pregnant with Van’s child.

Determined nothing will dull the shine of her new romance, Caroline joins the friends as they run wild through Greenhead, drinking on houseboats, gossiping on beaches while their children paddle, and playing risky games.

It seems the fun will last forever – until it doesn’t. As decades-old friendships and marriages begin to fracture, Caroline’s place in their world is called into question. And with all the group’s most tightly held secrets at stake, who knows what might come out?

Dazzlingly funny, sexy, and as juicy as it is astute, THE SHAMPOO EFFECT is a story of late-night parties, early mornings with small children, and old friends finally growing up – despite all their best efforts.
