In Metsan Valo, her family home on Lake Superior, Anni Halla's beloved grandmother has died. Among her fond memories, what Anni remembers most vividly is her grandmother's eerie yet enchanting storytelling. By firelight she spun tall tales of spirits in the nearby forest and waters who could heal--or harm--on a whim. But of course those were only stories...

The reading of the will now occasions a family reunion. Anni and her twin brother, their almost otherworldly mother, and relatives Anni hasn't seen in forever--some with good reason--are all brought back together under one roof that strains to hold all their tension. But it's not just Anni's family who is unsettled. Whispers wind through the woods. Laughter bursts from bubbling streams. Raps from unseen hands rupture on the walls. Fireflies swarm and nightmares stir. With each odd occurrence, Anni fears that her return has invited less a welcoming and more a warning.

When another tragedy strikes near home, Anni must dive headfirst into the mysterious happenings to discover the truth about her home, her family, and the wooded island's ancient lore. Plunging into the past may be the only way to save her family from whatever bedevils Metsan Valo.
