I tend to like readers a lot and follow them as much as I do authors. My top 2 are the two Simons--Prebble and Vance. They are both awesome. And my favorite female is Nadia May.
Frank Miller is an old favorite. If you have never read Call of the Wild, get the Frank Miller version. It's amazing.
Looking at my library for books I have listened to and particularly liked:
Amazing Maurice and his Educated Rodents -- Terry Pratchett
American Gods -- Neil Gaiman
A Crack in the Edge of the World -- Simon Winchester (he writes nonfiction and reads it himself, my friend finds him too dry and digressive but I adore him. It's like having an eccentric uncle who is an Oxford don go on about something he has studied in depth. I liked his book Krakatoa as well.)
Wee Free Men -- Terry Pratchett (I haven't gotten very far into the Discworld books but have really enjoyed these young adult ones).
Devil in the Details -- Jennifer Traig (OCD plus trying to practice orthodox judaism is not a good combination for sanity but boy is this a funny memoir)
Jonathan STrange and Mr. Norell -- Susanna Clarke (This and American Gods are enormous books that I think I would have had a hard time getting through reading but they were great companions on morning watch ) *Simon Prebble
The Nine -- Jeffrey Toobin (history of the Supreme Court, good stuff if you are curious about it at all but I imagine many would find it boring)
Stardust -- Neil Gaiman, read by Neil Gaiman. I could listen to Neil Gaiman read the phone book. Having him read his own books is a treat.
The Graveyard Book -- Neil Gaiman, also read by Gaiman
The Johnstown Flood -- David McCullough
Master and Commander -- Patick o'Brian (first in the series, read by Simon Vance)
The Bartimaeus Trilogy by Jonathan Stroud (supposedly YA but I wouldn't have liked it as a YA reader because the main character is such a jerk)
Currently listening to The Guns of August by Barbara Tuchman, read by Nadia May. Loving it.
I spared you all the urban fantasy and romance novels but if you are interested...Simon Prebble actually reads quite a few of the romances and he's great, even when it's a fluff story.
That should get you started!
