Sarah Waters The Little Stranger- The story of a haunted manor in the 1940s. It's a delicious little bridge between manor fiction- such as Austin, Bronte etc... and British war fiction. Waters has a Phd in Victorian literature and has put her research to marvelous use.
Don DeLillo Underworld- A wide ranging and ambitious novel of Americana.
Eudora Welty The Optimist's Daughter- A 1972 Pulitzer; A southern family novel, inspiration for the works of Anne Tyler.
Naomi Novik His Majesty's Dragon- A fascinating blend of military history and fantasy; the Napoleonic wars plus a dragon. Recommended to me by my friend Amber.
