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 dating Milo, Allie's super-genius hottie cousin!

Sequel to: Once every never.
