The Hidden Door (hardcover)

Across Time and Space Book 5 of 7.
¿¿Even seasoned time-travellers make mistakes.
After the near-disaster in Lile, 2598 AD, Ash and George are enjoying a well-deserved holiday in the twenty-first century and dreaming of what the future holds. But then Anne arrives suddenly, bringing news of a family emergency that calls him home to 1818, and sends Ash to the supernatural haven of Erastus to find answers. Great idea - until the gateway home is accidentally destroyed.
Meanwhile, Kamile is recovering from the events that killed her best friend. But even as her adopted family is exploring their new lives, her strained relationship with Aras seems an inch away from falling apart entirely. Helping Ash with her little stranding problem seems to be too much to manage.
But when a new danger arises, one that moves freely between the normal and Other realm, everyone must work together to defeat their common enemy. It's life or death, and they're about to find out what really lies through Erastus's beautiful stone archways...
