Daisy and Red are visiting the Zambezi River. An exciting adventure awaits, but they must listen to each other if they are to succeed. The Adventures of Daisy and Red: Moonbow Rescue is at Oxford Reading Level 11. It is for readers aged 7 to 11 years old who are working below expected standard in their reading. The Readerful Rise series ensures that older struggling readers have books with age-appropriate content and topics, that look like the books their peers are enjoying, but are written at a level they can read successfully.
