Life hasn't been entirely fair to Evan Sinclair, or 'Sissy Sinclair' as most of his classmates like to call him, but now it's seventh grade - and the universe owes him. A missing baseball bat, belonging to star player Jayden Stevens, provides him with the perfect chance to put his love of detective shows to good use. His objective? Find the lucky “lightning bat” and score himself a place with the most popular kids in school: The Untouchables.

However, just like in the TV shows, nothing goes according to plan. As Evan delves into the investigation, his personal life turns to shambles. His father's overbearing nature and extreme religious devotion lengthen the rift between them, while Evan is still processing the loss of his mother. His grandmother, his BFF and an unexpected old friend are the only people he can count on to help him crack the case.

There are numerous suspects in Lincoln Middle School, but this mystery goes deeper, becoming even more complicated than anyone first thought. Is it just petty jealousy that has fueled this theft? Or is something more sinister going on behind the scenes of the baseball team? There’s one person who won’t stop until he uncovers the culprit, even as he’s finally confronting his own deep dark secret; it’s Evan Sinclair.
