Double Up - Vanessa North

The conflict felt a little artificially manufactured to me

(why the hell would someone break up with someone they care about because they don't want to have surgery because they have problems with addiction?! I couldn't imagine someone actually doing that, out of the blue)

(show spoiler)

 and the solution a bit too easy

(so, your childhood friend has been on your case to have the surgery for 10 years, promising to support you afterwards if you develop addiction problems again, and you haven't done it, and a random sexy guy comes into your life, breaks up with you again, and you suddenly decide to do it? again, sounds extremely unrealistic)

(show spoiler)

, but the quality of writing is high, and the supporting characters great (especially Eddie!), so I still enjoyed reading this.
