"Guess what!" said Amy. "It's my birthday next week and my mum says I can invite all my special friends for a sleepover party."

You're invited to the ultimate sleepover!

Amy, Bella, Chloe, Daisy and Emily are best friends at school, they even have their own Alphabet Club (just look at their initials!). Daisy is the newest member, she's desperate to fit in, even though Chloe is VERY unfriendly to her at times.

And, when the girls start planning sleepovers for their birthdays, Daisy starts dreading her own.

She doesn't know what her friends will make of her older sister . .
