Ellie is ready to have the best summer ever. She's especially excited to draw under her favourite tree and hang out with her big brother, Ben. But all Ben seems to care about is impressing the new lip-glossy neighbour, Sara. And all Sara seems to care about is turning Ellie's brother into a Hawaii husband! Luckily, Ellie's best friend, Ling, has the marriage list-a top-secret tool to track the lovebirds and stop a wedding before it starts. But nothing goes to plan, and while trying to rescue Ben, Ellie ends up putting the weeping willow in her garden in danger. Faced with losing everything she loves most, can Ellie find a way to win back her brother and save her beloved tree? An utterly charming story about a lovable 10-year-old with Down's syndrome whose extra sparkle never fails to shine bright.
