Interesting conceit for a story. Seems more like a screen script to impose the arbitrary conceit 'we need lose the v-cards' before we get to uni but then, the story wouldn't have any sense of jeopardy without it. The dialogue is imaginative, sparky and very droll. The drama of female friendship is conveyed well. Sam and Hannah are well rounded characters and their voices shine in the writing. If I had one criticism it would be Hannah's grandmother who talked more like she was Hannah's peer at some points in the novel. That's a very minor criticism though as overall I enjoyed the novel. The dual perspective didn't feel cumbersome or drag the pace down.
