Salem on Trial (Sabrina the Teenage Witch, #8)

Nine lives sentenced!

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 she brings a charge of witchcraft against Sabrina and her cat-- and the judge sentences the time travellers to hanging!

Suddenly, Sabrina and Salem are trapped in the past with only their wits to escape the noose... and time is running out!
