Kirsty is a girl who loves spending time with her grandad on his allotment, but isn't too keen on spending weekends with her older half brother and sister, Ben and Dawn.
She gets on alright with Ben, but has to share a room with Dawn every weekend - something they both hate.
But everything changes after Kirsty's grandad dies and the council says his allotment must go to a stranger.
Kirsty has to get Ben and Dawn to help her change the council's mind and help their dad get over the loss of his dad.
Kirsty promises her sick grandad that she'll look after his treasured allotment when he dies.
Unfortunately, Mr Thomas from the council doesn't care about Kirsty's promise - he's got a waiting list for the allotment and Kirsty isn't on it.
So Kirsty has to persuade Ben and Dawn to help her in an elaborate plot to make Mr Thomas change his mind.
Meanwhile, Kirsty's dad isn't dealing well his dad's death at all and acts as if his kids don't exist.
But can their cunning plan, with elephants, skateboard rollerskates and late night stakeouts really put everything right?
Pretty much the whole thing.
It's easy to relate to Kirsty and although the story sounds as if it might be sad, there's still loads of funny bits.
None really, although if anyone in the real world did some of the things Kirsty gets up to they'd probably get into a lot more trouble!
Absolutely. It's a great story that races along, with each chapter leaving you desperate to find out what happens next.
