Is 'Doomhaven' Based On A Board Game Or Original Novel?

I’m the heroine in an erotic story. My specialty? Turning anything hot or cold into something steamy. On the first day I landed in a horror game, the boss told everyone to choose how they wanted to die. I smiled and said, “I’ll take shortness of breath, trembling legs, glazed eyes, and… pleasure so intense I die from it.” Boss: “???”

You think I care about titles?” he asked, stepping even closer until I could feel the heat radiating from him. “Do you think that matters to me?” “It should,” I said, my voice breaking slightly. “It matters to me.” He tilted his head slightly, studying me. "Why? Why does it matter so much to you?" “Because,” I said quickly, searching for the right words. “Because people like me... we don’t belong with people like you. You’re... you’re powerful, and I’m—” “Beautiful,” he cut me off, his voice firm. I froze, my words dying on my lips. “What?” I whispered. “You’re beautiful, Sophia,” he said again, his tone softer this time. “And I’m tired of pretending I don’t notice it. You think being a maid defines you, but it doesn’t. Not to me.”

Willa Roane dies the same night she catches her boyfriend in bed with her sister. Instead of waking in peace, she’s dragged onto a ghostly bus and informed—by a mocking intercom—that she’s entered the Survival Game: a twisted show where the dead are thrown into lethal, terrifying worlds for the cruel amusement of an unseen audience. The rule is simple: survive each round… or your soul is erased forever. Her only ally is Corvin Thorne, the devastatingly beautiful stranger who yanked her off the road and onto the bus. A hybrid vampire–werewolf with a past soaked in blood, Corvin is bound by a wicked secret contract to keep Willa alive… or forfeit his own soul to the game. As they descend deeper into the nightmare realms—from a monster-ruled Dracula Castle to ruined neon cities—Willa realizes she is the key. The deadly worlds are twisting around her darkest fears and fantasies, turning her own horror stories into elaborate traps. She isn’t just a player; she’s the author of the chaos. And the man sworn to protect her may be the only thing she can’t control. Now Willa must rely on the dangerous man she’s falling for, a man who swore he would never love again. The heat between them is undeniable, but as their bond deepens, it’s impossible to tell which is more dangerous: the monsters hunting them… or the love that could destroy them both. Love might be beautiful—but in this game, it’s never sweet. It’s a weapon, a weakness, and the one thing that might rewrite the rules of Hell itself: desire. ---

Isadora didn’t want to come to Ashwyck Academy. It wasn’t the haunting towers or the iron gates that unnerved her. It wasn’t the students—dark, beautiful, terrifying things cloaked in magic and menace. It was what it meant. Coming here was a last resort. A whispered admission from her parents that something was wrong with her. That despite being born of a temptress and a mind-bending killer, despite all the bloodlines and rituals and whispered prophecies—Isadora was still painfully, tragically human. She was quiet, clever, and careful. Not powerful. Not wicked. Not like the others. Her parents called it “late blooming.” The High Table called it “defective.” But no one said it out loud. Instead, they tucked her into Ashwyck like a final gamble and hoped the academy could awaken whatever dark inheritance slumbered beneath her skin. She hadn’t wanted to come. She still doesn’t belong. But Ashwyck has its own secrets. And Isadora is about to discover that the parts of her she’s most afraid of are the ones they’ve been waiting for.

The story is a dark psychological horror centered around a group of students trapped in a college during a curfew, where a storytelling game slowly turns terrifyingly real. I believe it aligns well with Good novel horror audience.
