Dearie me, I take it you have read said "latest Bob Galbraith offering" and are qualified to comment.
I have not, neither have I read the HP books nor the Strike books because, despite having endured several bum-numbing hours in the cinema accompanying DC I am not a fan of children's fantasy fiction. I am also not generally a fan of private detective fiction so I can't comment on the literary merits of JKR's prowess in either genre.
I have come to admire JKR because, yeah, she could have sat comfy in her not actually a castle, more of a big hoose., but she didn't, she's put herself out there, taken the flack that other women can't afford to take, literally put her money where her mouth is and hasn't backed down despite the most heinous and disgusting threats against her.
But all you've got is "nah, your mum".
Try again.
