More or less exactly what I expected. Reasonably light (in terms of prose), a quick read. It's definitely a solid three stars: the characters are likeable, and Winman fleshes them out well. If the narrative hadn't been so jumpy and incomprehensible in places, I would probably have given this four stars. Some things come out of the blue (dead baby jesus springs to mind) and aren't really all that relevant. Some things (like the boy who drowns and the guy Elly has sex with) are under-explained or never really fleshed out.
I liked it quite a bit though, despite it feeling a bit roughly put together. I'd read something else by her.
