Salem on trial - David Cody

When Sabrina has a history report due, she and Salem do some serious research - in Colonial-era Westbridge! Their temporal transit tickets are unchangeable and nonrefundable, and Sabrina's powers have been time-locked so that she won't accidentally change the course of history through magic.
Sabrina's first shock is meeting Harvard Kinklin and Libbeth Chestler - dead ringers for Harvey and Libby. Libbeth's as jealous as her alter ego when Harvard pays too much attention to Sabrina. So when she hears Sabrina speaking with Salem, she brings a charge of witchcraft - and the judge sentences the time travellers to hanging!
