Twin sisters Cath and Wren are starting university and although they've been joined at the hip all their lives, growing up sometimes means shooting off in opposite directions. Wren is a party-girl extrovert while Cath, our narrator, is an authorial introvert with a fandom obsession.

I loved the inclusion of Cath's fanfic writing alongside "excerpts" from the canon tales of fictional children's fantasy author Gemma T. Leslie's Simon Snow series. (A thinly veiled Harry Potter type fandom.) Cath's dilemmas, quirks, and fears really resonated for me. Although this was by no means a sad, melancholy or upsetting story, I often found myself in self-reflective tears over Cath's musings. (These were often followed directly by chuckles; Rowell's humour is paced excellently.)

I feel like if I handed this book to someone who doesn't know me that well and said, "please read this: I think it will explain me to you," that they'd have a pretty good grasp of me by the end of the novel. I've never felt that about a book before. An excellent read! Thank you for that, Ms. Rowell!
