Initial thoughts: Maybe I should've read
Can You Keep A Secret? before
I've Got Your Number because the latter was published much later in Sophie Kinsella's writing career and was way funnier. A lot of the times I wanted to smack the protagonist's head because she was so incredibly naive and shallow, it wasn't even funny anymore. At least there were believable instances and who doesn't dread office politics? So there's that. Had I read this book before
I've Got Your Number, I probably would've given it 3 stars because without comparison, it would've been a slight bit less painful to read. I know I spent a fair bit rolling my eyes. Although, as an early work, it did display Sophie Kinsella's ability to write well because the prose was pleasant to read.
