Access Denied (and other eighth grade error messages)

Book excerpt: Computer whiz Erin Swift is ready to start eighth grade. The Year of Humiliating Events (aka, seventh grade) is behind her and she's ready to rule the school. But eight grade comes with its own set of problems for Erin to navigate, including her first boyfriend, her first break-up, and the fact that her mom has been treating her more like an eight year old than an eighth grader. Even worse, there's a new girl at Molly Brown Middle School who is determined to remake Erin in her bad-girl image, and former crush Mark "Cute Boy" Sacks has been acting strange lately. But as Erin's school year once against hurdles toward disaster, a personal tragedy forces her to realize that things, and people, aren't always as bad as they seem. Can she save what's left of eighth grade before it's too late?
