Clemmie has a problem - she's had almost as many jobs as she's had birthdays and her lovelife is on the critical list. But with the big 3-0 looming, she's determined to transform herself from unemployed singleton to loved-up success.

He'd also be high on her list of candidates for significant other. But Guy has a veritable cargo hold of baggage - avaricious ex-wife and a host of monster ex-step children. He's not even looking for an assistant. And if he was, a quirky amateur firework maker with a penchant for cream cakes and big explosions wouldn't be high on his list . . .
