United Middle School Mysteries Book 15 - Paperback

by E. J. Rohly (Author)

When sealed test papers vanish from a locked office, four students at United Middle School start asking questions they are not supposed to ask.

Jake, Emily, Max and Amy follow the clues through missing files, false leads, and quiet lies, uncovering a desperate choice that should have ended the mystery.

Instead, a warning appears.
Signed with a single letter.

X.

Someone knows what they found and wants it left buried.

As the team digs deeper, the case turns into something bigger than a stolen test and far more dangerous than a prank. At United Middle School, some stories were erased on purpose, and the truth is waiting for someone brave enough to bring it back.
