Wolfed this down in two sittings -- last night and this morning. It's a fast-paced tight crime-cum-love story, but two types of love: family love (Ana's love for her younger sister Indie, rescued from Mum a few years before) and romantic love (her rekindled love/lust for old flame Sawyer, a cop). Both these loves, and a recent desperate act to save Indie, put her in a moral dilemma we see played out. This is plotted and written well, and the situation and characters believable. Jensen has delivered what she set out to, I think.
The fifth star I can't give only because I wanted more. There's such a rich subtext here that I would have liked Jessen to be a little more generous in developing the backstory and the characterisation of Mum and Indie; the brief glimpses felt too few and too late. It gave me the same feeling as watching an episode of a crime drama in which we follow the investigators but get a whole story of the dysfunctional family investigated...except that here we're meant to be following/knowing Ana, and we leave her just when her journey is getting interesting. There's something closed about this novel for me, something that ties it all up or lays it all out too much so that there's not a lot of room to sink into it and find my own way with the characters, the situation, the clues -- none of the journeying joy Orhan Pamuk writes about in "The Naive and the Sentimental Novelist". I don't think it's verse form is to blame, although that increases the challenge (fewer words to create the gaps). That's it, actually! She's called the work "Gap" but she hasn't left enough gaps lying around, within the text, for us to grasp: a bit like handholds/footholds we can use to climb down into a deeper story. But I read it quickly; there is skill here, so more time in a fresh read might prove it's me who's missed the opportunities, rather than the work.
