Forests of the heart - Charles de Lint

The old house Kellygnow, an artists' and writers' colony, welcomes and shelters those who are looking for a little more out of life, a little less reality. Bettina San Miguel is not an artist, but a model, who thought to stay at Kellygnow for only as long as it took to find an apartment in Newford . . .but a week turns into a month and before long she realises she's home.
Then the brujeria in her blood calls out to the spirits and she finds herself walking in myth time, that piece of the past or the future where the city didn't exist yet or is long gone, maybe. There she meets one of los lobos, the wolves, who are drawn to humanity, to take their warmth for their own . . .
