Where Are You Now?

Okay, so I picked out this novel by Mary Higgins Clark because I so thouroughly enjoyed Just Take My Heart. This one, however was a let down. It's about a young man named Mack who mysteriously went missing when it seemed he had his whole life ahead of him. He vanished except for one thing... He calls every mother's day. The novel is his little sister's personal search to find him, but she gets herself in over her head. The ending was too sensational and the suspence lacked the momentum to carry me through the novel. I found myself annoyed by the ending and this will be the last novel I pick up of Clark's for a while
