Query: Challenging and infuriating, but worth it.

If you read "Mrs.Dalloway" with an eye to plot it will be slow and its greatness will remain obscure.However, if a reader relaxes and lets herself enjoy the tender prose, and the emotional storm suffered by many characters(especially Septimus and his wife), Mrs. Dalloway will haunt the mind with its insights.Furthermore, reading "Mrs.Dalloway" is great preparation for its inspired (and there I say superior) contemporary sequel,"The Hours."
