In a flash, Lina, Chloe and Abeo's lives are changed forever. A silver cube has appeared and, with it, an opportunity to make a difference in the world. However, things don't go to plan ...

This book is from Readerful's Independent Library. It is for children aged 8 to 9 to read without support.

Readerful is a reading library specially designed to motivate children to read more. The series offers contemporary, inclusive books for children from 4 to 11 years, including:

Books for Sharing: picture books to be read aloud by an adult for inspiring reading sessions

Independent Library: fiction, graphic texts, character mini-series and non-fiction for children to read independently

Rise: fully decodable books for older struggling readers to read independently.

How Readerful works:
- Read aloud the Books for Sharing for magical reading sessions that motivate children to read more.
- Then encourage children to choose a book to read by themselves, from Readerful's Independent Library or from Rise. You'll find links between the books' topics, vocabulary, characters and authors - all designed to keep children reading, boost their vocabulary and develop their knowledge of the world around them.
