I listened to the two most recent Jennifer McMahon books:
The Winter People and
The Night Sister. I have read several previous McMahon titles; even though she includes supernatural elements that I usually avoid in my reading, for some reason I generally like her books anyway--the writing is suspenseful and usually not over-the-top silly.
The Winter People kept me intrigued. The author juggled several sets of characters and timelines deftly, but at one point it did get silly--McMahon seemed to need to move the plot along and seemed to choose a rather unbelievable way to do it. Plus the information dump when she's wrapping up seems like lazy writing. I always find it annoying when a character suddenly decides to explain everything that has gone on before.
The Night Sister was better. Again, there were several sets of characters and multiple timelines, and highly suspenseful scenes. The narrator (Cassandra Campbell) got a bit intense in her reading of some scenes, but it worked to add to the suspense.
