If you like a good ghost story, this book should satisfy you.
A young airplane pilot has to bring his commuter plane down in water. He performs a perfect execution, but a wave catches the plane and flips it. Several lives are lost.
As the pilot heals from his own injuries, he starts seeing the ghosts of some of those who died. He's unable to work and feels trapped in his town and by his nightmares.
His wife finds a big old house away from anyone they know and the couple move there with their twin daughters.
In this new community almost everyone has a greenhouse. The women all go by names of herbs and spices. They seem to be obsessed with the twins. Unfortunately, the move didn't get rid of the haints; they followed the family to the new address.
You'll be engrossed as you learn the connections among the twins, the herbs, and the residents of this community and all the way through to its chilling ending.
