This is one of those novels to which the term "poetic" attaches itself. This is usually a bad thing and 'The Truth About Love' doesn't buck the trend. From an sinkingly opaque stream-of-consciousness prologue, as a dying boy is ferried into hospital, the narrative proceeds as a series of first-person narratives, none of which manages to be authentic or convincing. I've given it two stars because somewhere, buried beneath the wishful thinking, is a potentially interesting meditation upon the nature of love and memory. My problem is that the various narrators' concepts of "love" -- which Hart, as organiser of the farce, doesn't seem to question, unless I'm missing a trick -- are ethereal and idealised to the point of evaporation.
I also struggled with the concept of Irishness that seeps into every corner: characters seem to exist in a curiously un-Irish state of unsceptical, self-conscious national(ist) fervour. The dialogue clunks desperately and lurches into sudden fits of exposition where characters address the reader over the head of the interlocutor. It's curious (and symptomatic of the book's pretensions) that a reference to "The Late Show" -- which anyone who hadn't lived in Ireland would probably find more problematic than mention of Pearse and Collins -- goes unglossed.
There is a bibliography.
