TUESDAY'S JOURNEY CONCLUDES IN THIS SPINE-TINGLING FINALE, THE EERIEST BOOK IN THE HALLO-TWEEN SERIES! Tuesday's mom and aunt are turning into junk food zombies, her uncle is nothing like himself, and somebody's let a whole group of monsters loose in town. Weirdness abounds when she and her friends try to solve the problems—and end up making them spookily worse. Is her enemy who she thinks it is? Or is the spookiness plaguing her whole town so much bigger than she realizes? In this conclusion to the Hallo-Tween series, Tuesday must confront the most evil enemy she's ever had, wrangle ghosts, monsters, and golems, and hopefully save her family along the way. Magic has never been scarier than it is now, but together with her best friends, Tuesday is up for the challenge.
