Goosebumps Wanted: The Haunted Mask is a stand-alone book in the Goosebumps franchise that geared up to the Most Wanted series. It is the first original Goosebumps book to be released in hardcover format. It was also released in paperback. It was first published in 2012.
The book is divided into four parts, a prologue that took place in 1972, Lu-Ann's story, which takes place 40 years later, Devin's story, and an epilogue called, "Polly's House".
Lu-Ann Franklin usually loves Halloween. Not this year. Her best friend, Devin O'Bannon, is going away for the week. And she has to go to a boring party where nothing exciting could ever happen. But when Lu-Ann comes face-to-face with the Haunted Mask, major trouble lies ahead.
Devin O'Bannon didn't want to leave his best friend Lu-Ann Franklin behind on Halloween. He didn't ask to go on this trip. And that was before he heard the strange scratching on his windows and saw the shadows moving around in the fields. Something is out there and it doesn't seem to want Devin around!
