My car commute book is "The Blue Hour" by T. Jefferson parker. This is a rather disappointing novel with plot holes you can drive a truck through, characters that one page are too weak to hold up a book and the next day is body-surfing to applause, pages of thoughts/feelings in the middle of a conversation, etc. A socially dysfunctional serial killer that seems so self-absorbed that he can barely function but manages to elude detection or capture for years. The parts ... just do not fit together.
For my workout MP3 player I just finished "Drybone Hollow" by John Billheimer. It turns out this is the 4 th book in the series but while previous events were mentioned, it did not mean I could not enjoy the story. The narration was good with accents that added to the novel.
I have just started "The Eleventh Commandment" by Jeffery Archer. In about 30 minutes I am eager to go back to the gym to listen to more.
