Publisher's Synopsis
Best friends Clare and Allie once more find themselves in trouble-and travelling in time. Taking part in an archaeological dig at Glastonbury Tor in England, the girls promise each other:
no time travel shenanigans, no involvement with dangerous Druids or villainous museum thieves, and definitely no weirdness about the fact that Clare is now seriously dating Milo, Allie's super-genius hottie cousin!
But when Allie makes an unexpected find at the dig site, the grisly artifact sends her spiraling back in time to a Roman encampment besieged by rampaging Celts. As she struggles to survive in the past, Clare and Milo race desperately against time in the present to bring Allie home … before she loses her head or her heart.
