Where should I go for inspiration?

As some of you may know, I’ve been working on a work of young adult fiction for a while.

I’m currently seven chapters, 17,000 words, and numerous revisions in and I need some inspiration to keep me motivated. A number of books initially inspired me to write the story I’m working on, most of which are novels aimed at young adults: Perks of Being a Wallflower, Staying Fat for Sarah Byrnes, The Lovely Bones, and Looking for Alaska.

All of these books have in common a coming of age theme, as well as a nostalgic, almost bittersweet sort of feel to them that initially inspired me to try my hand at the young adult genre.

Emulating and drawing from these works is no longer enough, though. I need new young adult novels to draw inspiration from and I don’t know where to begin. I do have a few parameters to help narrow my search:

Suggested books must be reasonably realistic or at least believable. Slight off-beatness is okay, of course (I mean, hell, the protagonist of the Lovely Bones tells her story from the afterlife, but it still feels real) No vampires or kids shooting fireballs out of their hands to fight the KGB on the moon.

Suggested books preferably contain some romantic or sexually tense material. My novel is a love story between an asocial college freshman and an enigmatic senior girl and I need to see how other YA authors treat these types of relationships.

Suggested books should be modern. Elizabeth Wayland Ellington wandering on the moors in Victorian England isn’t going to inspire me as much as a shy boy who writes anonymous letters to his dream girl in 1999.

Edgy content is always a plus. That’s a big part of what YA fiction is all about, and my own work contains plenty of it. I just like to see what other authors do.

It is also important to note that I am not seeking works to copy, nor have I plagiarized any of the above works I mentioned as being primary inspirations. The main draw the aforementioned books have for me isn’t so much the content as the feelings the content evokes in me (which in turn, inspires me to write). I’m simply looking for similar books or other works that fit my criteria and potentially evoke that same emotion, which will hopefully inspire me to keep hammering out my own work.

I’m posting this in general, but as is always the case with me, banter is welcome, and thank you in advance, my dear Flutherites.
