This book feels like it’s trivialising the serious subjects it contains. There’s definitely a place for humour in murder mystery/thriller books (Thursday Murder Club is a great example), but not when the 'humour' reads as if it’s making light of terrible circumstances.
 
I also didn’t find it funny, and there were WAAY too many ‘sticky kid’ descriptions. I already know I don’t want kids, no need to labour the point.
