Thunder on the Right — Mary Stewart

Artist Jennifer Silver has traveled to the picturesque, secluded Valley of the Storms in the French Pyrenees to meet with her young cousin Gillian, who is about to enter the Convent of Our Lady of the Storms. She had come to the convent--a brooding cluster of ancient buildings nestled deep in the wild upper reaches of the Pyrenees--to discover that the young woman has died in a dreadful car accident. Or did she?

The convent was not like others. There was something strange and frightening about the place... something that gave off an aura of evil, of hidden, violent things... Searching out the truth meant trouble. Lies abound in this strange and frightening place, but seeking the truth could lead Jennifer to one murderer. She did not know, until too late, it also meant... her own violent death.
