For fans of the Wilderlore and Skandar series comes a thrilling middle grade fantasy adventure steeped in Welsh myths and legends about two intrepid friends who are tricked into opening the door to an enchanted world—only to get trapped inside.

On a summer holiday in Wales, Portia and Ben find a mysterious door set in a bramble hedge in the middle of a forest. If the old stories about the wonders and dangers of the Otherworld hadn’t long been forgotten, they may have realized the door was a portal to the perilous realm and should never be opened…

Robin Goodfellow, the man with the fox shadow, needs someone to open the door in the brambles so he can finally return home, and he’s willing to use the children’s curiosity to his advantage and lures Portia under the guise of his innocent fox form.

Once the portal is open, great danger arises, and Ben and Portia struggle to stop a powerful evil threatening both the human and the fairy worlds as they find themselves stuck in the wrong realm.
