Homebody - Orson Scott Card

From a New York Times–bestseller, "a powerful tale of healing and redemption that skillfully balances supernatural horrors with spiritual uplift" (Publishers Weekly).
Don Lark's cheery name belies his tragic past. When his alcoholic ex-wife killed their daughter in a car wreck, he retreated from the world. Only the prospect of putting a roof over other people's heads seems to comfort Lark, and he goes from town to town, looking for dilapidated houses he can buy, restore and resell at a profit. In Greensboro, North Carolina, Lark finds his biggest challenge yet—a huge, sturdy, gorgeous shell that's suffered almost a century of abuse at the hands of greedy landlords and transient tenants. As he sinks his teeth into this new project, Lark's new neighborhood starts to work its charms on him. He strikes up a romance with the wry real estate agent who sold him the house. His neighbors, two charming, chatty old ladies, ply him endlessly with delicious Southern cooking. Even Sylvie, the squatter Lark was once desperate to evict from the old house, is now growing on him.
But when Lark unearths an old tunnel in the cellar, the house's enchantments start to turn ominous. Sylvie turns cantankerous, even dangerous. Lark embarks on a struggle for his life — and his friends'— against a house with a past even more tragic than his own. If Lark wins, he gets the kind of home and community he's always dreamed of. If he loses, all is lost. . . .
