The Price of Salt by Patricia Highsmith was a very good novel, with great psychological depth and a realistic depiction of all romantic relationships as complicated and messy, but with a hopeful ending after emotional turmoil.
I have just started Twelve Years a Slave by Solomon Northup (1853;2014 Dover press edition of their 1970 reprint of the 1854 edition, with their 1970 introduction). Source of the recent film. This is the true first person account of a man who was born free in New York state, then later kidnapped and sold into slavery in Louisiana. So far the author's elegant and formal style seems to provide a powerful contrast with the horrors depicted.
