The Girl Who Cried Monster (Goosebumps Series #8)

SHE’S TELLING THE TRUTH . . . BUT NO ONE BELIEVES HER.

Lucy likes to tell monster stories. She’s told so many that her friends and family are sick of it.
Then one day Lucy discovers a real, live monster: the librarian in charge of the summer reading program.
Too bad Lucy’s told so many monster tall tales.
Too bad no one believes a word she says. Too bad the monster knows who she is . . .
. . . and is coming after her next.
