Doll Maker (A Weirdville Book)

When Derek tells his friends, Martin and Jamie, about the new shop with creepy human-like dolls, they want to see for themselves. That has "bad idea" written all over it, but he takes his friends there anyway.

They meet the mysterious doll maker, who reminds Derek of Dr. Frankenstein, and who brainwashes Martin into buying one of those scary dolls. Derek and Jamie push and pull Martin out of the shop, but something isn't right with their friend. He's shivering all over, and he has no memory of what happened in the shop.

Martin's condition worsens every day, and Derek's sister grows more and more obsessed with her new doll. Derek and Jamie have to find out what's going on, and fast, because...

...the doll maker seems linked to a bunch of mysterious disappearances, and the last thing Derek wants is his sister, or his friend, being next on the doll maker's list.
