I refused to read Cockroach
May I ask what your objection is to Cockroach? (I haven't read it either...)
BTW, I don't really want to read The Orenda because I understand there are some graphic torture scenes in it.
I read Rawi Hage's De Niro's Game when it came out and I was less than impressed with it. The style was choppy and the characters were not at all likeable. From what I know of Cockroach it sounds like very much the same style so not worth investing my time in.
The Orenda does have graphic torture scenes and they are difficult to read. BUT they are not at all gratuitous and the ending would not make sense without them. I had to make sure I didn't read them just before bed time but otherwise they didn't bother me. There are also scenes of great beauty and comic scenes and love making and everything is gorgeously written. You really should read read it.
