Time's Revenge - Time Portals, #2

After her adventures in Time Portals of Norwich, Cassie Fox makes a promise to both her grandfather and her best friend, Georgia, never to time travel again. So, how did she end up in the deep past with her recent memories wiped, and her time-travelling abilities gone? Is she being punished? Did she press the big red button? Will she ever see her grandfather and friends again? And what has Robert Kett and his rebellion got to do with it all? Of more immediate concern, though, are the pains in her stomach.
