Rida and Madiya may have the same mum, but that's about all they have in common. They argue about everything, and when they find out the local library is in trouble, their competition over who can raise the most money only ends up making things worse between them! Working together might be the only way to save the library, but can the sisters put their differences aside to do it? This heart-warming story of siblinghood features beautiful black-and-white illustrations by Umair Najeeb Khan.
