Lulu Bell and the Birthday Unicorn

The series is aimed at younger readers of 6 to 9.
Lulu Bell is a fun-loving, sometimes bossy eight-year-old girl - the practical one in a slightly zany family. Her sister, Rosie, is six and loves to wear angel wings and sparkly shoes. Her brother of three likes to wear his superhero suit, even in the bath.
Lulu's mum is an artist and her dad a busy vet. Their home is right behind the vet hospital, so Lulu helps her dad care for injured and orphaned animals. No wonder they have lots of pets.
It's almost time for Rosie's birthday party. But there's a problem! A pony is running loose and Lulu and her dad, the local vet, have to rescue it.
Can they find the pony? And what will happen if the naughty pony gets into more mischief at the party?
It's lucky that Lulu has a plan!
