Whisper Woods by Ali Woods

For seven hundred years the city of Tathys has remained hidden from the world. But now the ancient magic is failing, and it is up to Rafe Miyares to find out why. All roads lead back to wolf shifter Seff Harroway—the man who’s haunted him like a dream for the last five years.
For five years they’ve met in the Whisper Woods. Destined to find each other again and again—but only for a single night. Secret moments in time, stolen from reality. Until worlds collide and the Gods decree nothing will be the same again.

Whisper Woods is the final book in the Legends of the Whisper Woods series. While each book contains its own HEA, interconnecting storylines throughout the series mean they are best read in order.
