I really wish that this had been expanded into a fuller book. Marr definitely would earn brownie points by expanding the Leslie-Niall-Irial triangle. Actually, I'd love to get into the nitty gritty of it. It wasn't something I expected at all, but I think with the Gancanaghs a polyamorous, three way relationship would fit nicely into Wicked Lovely. Looking back (I read this after finishing Darkest Mercy), the same could almost be said about Aislinn-Keenan-Donia, seeing as Aislinn was truly falling in love with Keenan at various points, but quite obviously not all parties are in agreement there. And not to mention that I really don't care for Donia. 
 The writing itself needed to be more developed. Maybe I was reading too quickly but there were some parts that didn't flow well or I was missing enough description to connect the actions in the scenes. For example (view spoiler)[ did Leslie actually push Ren down the stairs? (hide spoiler)] So in my opinion this was a rough draft for something far greater. Such a shame it was wasted in a miniature side story.
