Sleeping Freshmen Never Lie by David Lubar

Starting high school is never easy. Seniors take your lunch money. Girls you've known forever are suddenly beautiful and unattainable. And you can never get enough sleep. Could there be a worse time for Scott's mother to announce she's pregnant? Scott decides high school would be a lot less overwhelming if it came with a survival manual, so he begins to write down tips for his new sibling. Meanwhile, he's trying his best to capture the attention of Julia, the freshman goddess. In the process, Scott manages to become involved in nearly everything the school has to offer. So while he tries to find his place in the confusing world of high school, win Julia's heart, and keep his sanity, Scott will be recording all the details for his sibling's-and your-enjoyment.
