Brad, Conor and Scott are bored. That is, until they find the briefcase. When they discover a mobile number, it leads them from clue to clue to a cold, damp cave. But what is at the end of the trail?This hi-lo series for struggling and reluctant readers has been written for children aged between 12 and 14 years, whose current reading age is 7.5 to 8 years. These age-appropriate short reads have 32 pages and are written by talented authors.  They use a large font size, and the language and sentence structure are intentionally written so that students who are reading behind their chronological age can succeed in reading them. The series has plenty of practice at one level, allowing consolidation of learning before moving on to more challenging reads.
