I plan on reading William Faulkner's The Snopes trilogy, which includes (in order) The Hamlet (1940), The Town (1957), The Mansion (1959) and the prequel short story Barn Burning.

Excluding fantasy series (which obviously come in installments), do you have similar reading projects for this year? Or maybe you already read a trilogy, tetralogy or saga that you'd like to share. In which case, do tell.
