It's Rachel's mum's birthday and, since the Sisters have a day off, they decide to cook something special for her. Unfortunately things don't go to plan. The girls end up with a kitchen in chaos and nothing to show for it but burnt sausages and half a collapsed cake.

How are they going to get out of this one? Even Siti can't come up with an answer. This book is part of the very popular series Siti's Sisters, featuring Siti and her group of friends, who are so close they call themselves The Sisters.
