- Being fully within the character's head/Becoming the narrator -- Princess doesn't talk about her "junk" and Butch never considers fuchsia a fabulous color
- Revealing tidbits as the character learns about them -- Unless Barfy has x-ray vision, he's not going to know about the bogeyman lurking behind the door
- Seeing settings and behaviors through the character's eyes -- Snuggles can't see the malevolent storm rolling from the north if she's under the bed
The death trap of First Person writing is when the prose sound like a beast with its tail caught in the door.
Can you hear it? "I...I...I...I" Yes, it makes you want to run from it while your ears bleed or dash in and save it while your eyes bleed. Either way, the reader is no longer focused on the story but on salvation. In fairness to the authors, kaiyaiing is a second revision edit. Remember:I stalked the werebeast, my blade held high. I moved when it moved. I peed when it peed. I was almost done when it squatted lower. I couldn't do that. There was poison ivy at my feet.
First draft = story spewed pages. Second draft = clean up on aisle seven.
Some readers will chuck a book if it's written in First Person. I'm not one of them unless someone is attempting it in romance. I have yet to read a He-Loves-Me He-Loves-Me-Not (published or hoping to be) written in First Person that made me feel the love and the passion. That genre lends itself to the titillation of third person, possibly because there should be a "her" POV and a "him" POV. If it's all "I, I, I," the reader suffers a crisis of gender and sexual preference with a little dash of androgyny. Intriguing character complication in some genres, but not suitable for mainstream romance.
For those intrepid writers who love the First Person, please, be kind to your Betas and save them from the kaiyaiing beasts.
