I just completed the unabridged audio edition of Waiting by Frank M. Robinson. This thriller explores an interesting premise, but the execution is lacking. The motivations and thought processes of the characters are particularly inconsistent: the protagonist completely misses some obvious connections, yet makes other connections long before they are clear. But, as a thriller, I guess it fulfilled its most basic function: I was eager to get to the end to see how everthing was resolved, even though I was not too thrilled about getting through to the end.
Oh, and an additional minor annoyance: the reader of the audio book frequently emphasized what I thought was the wrong word in the sentence.
