I totally feel the same way. My own novel is so complicated as to plot, I'm scared to write a synopsis because I'm afraid to leave out important information, and not make it sound as terrific and awesome as it is!!! (Sorry for that.)

I'm totally waiting for tips!

Top!

Heh. I'm terrible at synopses. I always sound super pretentious and full of myself when I write them; I blame movie taglines for invading my brain at a young age. Generally though, I try to keep them concise and interesting, which generally translates to ambiguous and overdramatic because if there's one thing I'm really terrible at, it's being concise. Which... well, you knew that.

The goal, I think, is to make the reader excited about reading the story, which means it ought to set everything up as much as possible for the beginning and rising action, without actually giving anything away. Keeping secrets is a key to good writing, because you want the reader to always be surprised by your plot twists and nothing spoils a good book like overly heavy foreshadowing. So that ought to hold true for synopses as well, while still making the synopsis a kind of story in its own right. Which is why it's so difficult, I think. I don't know.
