The Hollow — Nora Roberts

For Fox, Caleb, Gage, and the other residents of Hawkins Hollow, the number seven portends doom--ever since, as boys, they freed a demon trapped for centuries when their blood spilled upon the Pagan Stone ...

Their innocent bonding ritual led to seven days of madness, every seven years. And now, as the dreaded seventh month looms before them, the men can feel the storm brewing. Already they are plagued by visions of death and destruction. But this year they are better prepared, joined in their battle by three women who have come to the Hollow. Layla, Quinn, and Cybil are somehow connected to the demon, just as the men are connected to the force that trapped it.

Since that fateful day at the Pagan Stone, town lawyer Fox has been able to see into others' minds, a talent he shares with Layla. He must earn her trust, because their link will help fight the darkness that threatens to engulf the town. But Layla is having trouble coming to terms with her newfound ability--and with this intimate connection to Fox. She knows that once she opens her mind, she'll have no defense against the desire that threatens to consume them both . . .
