This is probably more of a 2.5 in terms of enjoyment, but I'm rounding it up to a 3 because I think Connolly achieved exactly what he wanted to with this dark 'comedy of manners' style novel.
Poor Souls takes place during one hellish week in 1985 in London, and follows two couples and the other hapless people they come in contact with, as they essentially destroy both their own and each others' lives. There's a quote on the back of this book likening Connolly's writing to Bret Easton Ellis's if he had been born in Hampstead, and I'd really agree with that comparison. This novel is brutal at times, depressing, wryly funny, and unfortunately at the end of it all leaves you feeling utterly hopeless.
I haven't seen many people talk about this book at all, which is quite a novel (forgive the pun) experience these days on Goodreads - part of me wondered if this 1995 novel was still in print (amazingly yes!). I picked it up a few years ago in Fopp based on the weirdly ugly cover and the brief synopsis. And I'm glad I read it because Connolly is obviously really talented at what he does. The book is heavily based on dialogue and internal monologue, and the voices are so authentic that you could swear you'd encountered the characters somewhere before. As a character study, it's a really solid book. Unfortunately though I just think it was a bit too nihilistic, even for me. While I can appreciate the skill in creating these truly despicable characters, it was exhausting to hear them be just awful to each other, and watch them make continuously horrible decisions. Especially Barry, he was the absolute worst. There's also a lot of misogyny in the book, and while it is there for a reason and absolutely not the opinion of the author obviously, it got really hard to stomach after a while.
Overall this was a really interesting book and very different from what I normally pick up, and I can 100% say that it was an experience from start to finish. It went places that I didn't expect it to go, and got so dark at points that I was genuinely shocked. But, I think I'm going to have to wait a fair bit before I decide whether or not I want to delve into any of Connolly's other work in the future.
