I'm halfway through Joshua Ferris' Then We Came to the End and so far I am really enjoying it. I think it's the only book I've ever read that employed the plural first person ("we"), and while it takes a little getting used to, it works quite well with the subject matter (office life). There is one section that is in the third person, and although this could have been clunky, I found it entirely appropriate.
It's hard to explain what the novel is about; mostly it's about the intricacies of office relationships--friendships, rivalries, romances, personal traumas. On the surface it can read as quite fluffy and inconsequential, but the author does actually address surprisingly big issues like mortality, loneliness, what makes for a meaningful life, bullying and groupthink.
I'd recommend it for anyone looking for a pretty easy summer read that is just unusual enough not to feel like brain candy.
