Demographically, reluctant readers are three times more likely to be boys than girls¹. They also tend to have a narrower reading focus, subject matter-wise. When examining the problem of reluctant readers, researchers and teachers have determined that what makes a good reader is, simply, more time spent reading. That is, a child's reading fluency increases as they have more opportunities to practice, especially when their practice meets with a high level of success^2,3.

In response to the growing need for reading material to assist reluctant readers, a sub-genre has emerged: Hi/Lo books -- high interest, low reading level (also "low vocabulary" or "low ability"). Aimed at children in the intermediate grades, middle through high school, these books are short, running from 400 to 1,200 words, with many illustrations. They are packaged to look like traditional chapter books so that struggling readers are not further stigmatized -- especially important since struggling readers are probably already suffering self-esteem problems due to their reading difficulties.

Works for reluctant readers share many of the qualities that works for fluent readers do. They have strong characterization, featuring realistic protagonists that readers truly care about, with exciting storylines about interest topics. The best Hi/Lo books will appeal to both fluent readers as well as reluctant readers; the fluent readers will simply be able to get through them quicker.

However, Hi/Lo books must also provide supports that can assist the reading abilities of a struggling reader:

• Characters, in addition to being compelling and three-dimensional, must also be immediately distinct from each other, all without relying on copious description or slower-paced character development. Writers don't have the luxury of long, description-laden passages in Hi/Lo books or they risk losing their audience. A simple technique writers can use is to ensure that the names are visually dissimilar from each other.
  
  
• Longer words and sentences and less commonly used vocabulary words increase reading difficulty level^4,5. Harder vocabulary items should be introduced within contexts that make their meaning clear. Writers also need to make sure these vocabulary words are repeated in order to reinforce their acquisition.
  
  
• Sentence structure should be short, simple, and clear. Authors should break longer sentences into multiple sentences, and use tight, concrete writing. Style needs to be consistent throughout, without the typical increases and decreases of reading complexity found in more traditional texts.
  
  
• Plot and storyline presentation must be straightforward, without point of view switches or non-linear chronologic progressions. Flashbacks, plot twists, and red herrings should be avoided in order to better progress the reader swiftly through the story. Tight, fast pacing is essential.
  
  
• Subject matter for Hi/Lo books must be geared to children's, but particularly boys', interests and should be something readers have an easy time becoming emotionally invested in. Readers must to be able to connect their own experiences to the text in order for it to resonate with them. Writers who wish to write material for reluctant readers need to be up-to-date on what kids at that age are interested in. Nonfiction is especially appealing to boys because it's both easy to find titles that focus on a specific interest and the reader doesn't need to read the entire text in order to obtain benefit. Some popular topics include funny situations, sports, disasters, teen conflict, family/friend problems, and street kids/gangs (rebellious boy saves the day). Genres include science fiction, mystery/spy, and adventure.
