The following review may contain spoilers.
Noelle is missing. Reed is receiving anonymous texts from Noelle’s kidnappers. In order for Noelle to be found alive, Reed must complete four assignments and by no means go to the police or solicit anyone’s help. Reed performs the assignments and awaits Noelle’s outcome.
Eventually Reed and Noelle are reunited and the truth surrounding Noelle’s disappearance is revealed. The twist is meant to be shocking, but it’s so random (and anticlimactic) that I ended up not caring. However, the twist is a good segue for The Book of Spells, the next is the series focusing on the original Billings Girls. Its release date is December 21, 2010.
