For male narrators I've always preferred Scott Brick, on the female side I like January LaVoy. I like both of these people so much that their voices have become the voices of the characters January is Kay Scarpetta to me.

The thing that is odd for me this year is I took a shine to westerns both classics like Larry McMurtry to moderns like the Johnstone's. I don't know what drove that switch but it seems to have tangentially stuck because there's quite a bit of C.J. Box of the bit.
