You can't write if you're not in the mood. Do something that inspires you like going for a walk, listening to music, thinking about memories etc. Don't write anything if you feel like you have nothing to write because you'll just be disappointed and frustrated. Good luck.
maybe a novel about teens that fall in love? You can make them.. something paranomal.. like umm.. vampires? You could do a book about a teenag vampire that falls in love with a vampire from an opposing clan or something.. you could put horror and thrillerness in it..=] idk..
you're a genius when it comes to a genre to a book. i love it when a book has all of those in one!
well i don't really have any ideas because i used them all up on the book im writing, but good luck!
