One of the things I love about Campbell's writing is that she keeps the pace up without bogging it down with navel-gazing prose or "poetic" asides. While these books (and their characters) may be too gritty for some (or many, let's be honest here), the IMA series is worth your while if you like your fiction dark and your thrillers unpredictable.
I will say that there were some typos, and a few plot points seemed bizarre, but nothing that made me roll my eyes or scoff in disbelief. I will also say that if this is the last book in the series, I will hunt Nenia down and court her with pizza and booze until she keeps these books going.
And yes, there's sex in this book, and yeah, it's hot. Let the good times roll, as Michael would say...
But the reason it's hot is the same reason why I'm hooked onto this series: Campbell makes you care about the characters. Even those that are truly detestable are fascinating, so you want to know what happens next, and why.
L&L left me with questions unanswered, and with me wanting more. I cannot wait for the next book (because there damn well better be another book, Nenia).
