Waywarden by S.A. Harian

In the thrilling second installment of the Briardark series, three paths diverge, uncovering revelations buried within an impossible wilderness.

Separated from her team and haunted by grief, Siena Dupont claws her way through the lightless Briardark in search of an escape. The final threads of her sanity unravel when she realizes The Shadow isn’t the only thing stalking her through the forest’s darkest depths.
Cameron Yarrow has long abandoned her team in pursuit of a ghost from her past. Desperation drives her to the depraved settlement of The Tooth, where a terrifying ritual ensnares her. To survive, she must place her trust in a stranger and embrace the trail of clues to Avery Mathis, the crux of her obsession.
Holden Sharpe refuses to let Siena vanish, even if it means embarrassing himself as a rescue mission amateur. But when a raging wildfire derails the search, he must find another path to the missing researchers—even if it means confronting the boundaries of reality itself.
