Bobby the dog lived 150 years ago. This is his story and his loyalty is a lesson to us all.

Best Friends is a book-banded reading book for developing readers, carefully levelled at Orange Book Band for guided reading.

Illustrated throughout with beautiful photographs, this non-fiction title is suitable for struggling teen and adult readers.

Best Friends features a longer, less structured text with a more extended vocabulary.

More literary language is used with more complex sentence structures.

More space is allowed for text than for pictures. Best Friends is part of Ransom's Neutron Stars, a structured reading programme for teens and adults learning the basics of reading.

The series offers progression through ten levels of reading, four phonics and six coloured book bands. More information on the structure of the scheme can be found here.
