Not my style of book, pleasant read but bit of a tired premise

I have not read much of Kamila Shamsie's work so a relative newbie to her writing. I have, however, read an excellent book about teenage female friendships in the past (this one set in Singapore and the US, Sharlene Teo's 'Ponti') and I couldn't help but compare the two. It feels in places like Shamsie is ofen talking about the characters' bond with an expectation that the reader will imagine for themselves how that bond manifested rather than showing the reader via dialogue and plot points. I must say I have read quite a few novels now on the well-to-do ends of the South Asian diaspora in the UK/the US, and what I consider the interesting parts of that - the background of what maybe went on in the home country prior - is often transformed into a quickly touched upon backstory. That is the case here as well, and it is likely simply down to personal reading preferences that the novel didn't quite resonate with me as it felt like a bit of a tired premise, despite the supposed novelty of being about female friendships.
