Even as I was reading House of Hunger in its very first chapters, I wanted it to be so much longer. I got hints of the Gothic tone I believe the author was going for, I just don't feel like she indulged in it quite enough. The first few chapters fly by, which isn't a terrible thing necessarily because I did prefer the setting of the House itself, but even when we got there things just continued zipping along. I wanted to spend more time in that world of debauchery and blood, lust and vampires. The inklings of a truly Gothic atmosphere we got were incredible and there were some wonderfully dramatic bits of dialogue, I again just wish that more time was spent building and intensifying that vibe (especially that debauchery aspect; this book could've been way more descriptive and reveled in the vice-riddled world of aristocratic vampires). 
Even though the descriptions were generally very well-written, there were some aspects of the writing style that I found repetitive and a little boring (e.g. the phrase "Just then," is used far too frequently and often probably doesn't even need to be used at all). 
All that being said, if you want a well-done contemporary sapphic Gothic novel about hedonistic, aristocratic vampires and the poor girls who get pulled into that world, House of Hunger is certainly worth checking out.
