The Witch's Amulet — Lucy Ruggles

Trouble's brewing in Halloweentown!

Summer has arrived in Halloweentown, but for Marnie Piper that doesn't mean beaches, suntans, and ice cream. It means trouble. As a resident advisor at Witch University's Summer Sorcery School, it is up to Marnie to keep an eye on all the students -- including her sister, Sophie.

Then Sophie goes missing, and Marnie suspects that there is bad magic behind the disappearance. Her suspicions are confirmed when the Gift -- a powerful amulet belonging to her family -- goes missing as well. With time running out, will Marnie be able to figure out who is behind the mystery? Or will her entire family fall under the spell of a powerful and dangerous warlock?
