The Weird Sisters by Eleanor Brown

When their mother takes sick, three adult sisters return to the roost. But each has ulterior motives for her stay - pregnancy, thievery, insecurity - which make their challenging familial relationships even more fraught.

I enjoyed the story - it's about self-discovery and how we limit and define ourselves based on our family - but it's pretty much contemporary chick-lit for the literate.

The "weird sisters" of the title refers to Macbeth's witches, rather than any real oddity in the novel's main trio. That said, you'd best be familiar with Shakespeare's life works to be comfortable in this novel - it's overflowing with people named after characters and conversations filled with quotes. Additionally, the story contains layer upon layer of references and analogies to the bard's work.

Also of note: the story is told from a very unusual point of view. The omniscient narrator speaks singularly as all three sisters collectively (first-person plural). Everything is "we" even when talking about one sister's secrets that she's keeping from the others. It's workable, but a little awkward sometimes.
