I lean toward non-fiction
"1913" by Oliver DeMille (A lot of his stuff is good)
I also lean toward dark stuff:
"Blackbird: A Childhood Lost and Found" by Jennifer Lauck
Fictional dark author is: A. M. Homes like "Music for Torching" and "The Safety of Objects". Her book "Jack" is particularly disturbing
Along the theme of disturbing, the classic "Lolita" by Vladimir Nabokov is a once in a life-time read although classics like "The Handmaids Tale" by Margaret Atwood, "Atlas Shrugged" by Ayn Rand, and "The Scarlet Letter" by Nathaniel Hawthorne might be worthy of a re-read.
The scariest science fiction I ever read was "Swan Song" by Robert McCammon
My husband leans toward Lee Childs.
For light reading, I enjoy David Sedaris (and is sister write, too).
On my to read list is "The Gulag Archipelago" by Alexander Solzhenitsyn (no Kindle version yet and I haven't found it in a used book store) and "Behold a Pale Horse" by William Cooper (along the way, I found "Upon a Pale Horse" by Russell Blake and that looks good, too).
As a family we read aloud each evening. These are more kid friendly books since my child is a pre-teen. The classic "Treasure Island" was good, but very long. We look forward to reading "The Wizard of Oz" soon. We've read some Sherlock Holmes. We're right now reading the "I.Q." series by Roland Smith and next in line is "Divergent" by Veronica Roth.
BTW, I love getting book recommends!
