There are stories which are better written first person. First person is the most intimate of voices. It puts the reader in the head of the character. He gets to live the story along with the character. He can't know what the other character's are thinking, however. The teller of the story might guess at times what they're thinking, but he can't "know." If you just have one person telling "his" story, first person is hard to beat.
There are different kinds of third person voice. There is, of course, the omniscient, godlike, third person voice who sees everything and knows everything, even what the characters are thinking. The problem with that kind of third person is that you tend to lose intimacy. Orson Scott Card in his "Seventh Son" (Alvin) series uses a third person voice that I like. He puts you in different minds at different times, using third person, but speaking with the voice of that particular individual. If it's a kid, it's the voice of a kid, possibly using words like ain't. If it's an educated adult, it's the voice of an adult.
Here's an example of how that might have been accomplished with "Summer."
"How do you like it, Kelly?"
The question had been posed to Kelly by his twelve year-old cousin, Josh, who he was visiting in Santa Cruz. Kelly was visiting his Aunt Anna and her son Josh for a week. Although he hadn't seen Josh for three years, they'd hit it off right away, spending the day at the boardwalk at the beach in Santa Cruz. The boardwalk was old and a little seedy, but had been fun. Kelly thought that Josh was a beautiful boy; he looked like a young Aaron Carter-the sort of boy that every parent would want.
He wondered, though. Was he really a boy? Had he been done? Done, as in castrated? He couldn't very well ask him, though. If Josh hadn't been castrated, he'd wonder why Kelly was asking such a question. What could he say, "Josh, I was just wondering if you have any genitals-because I don't." Kelly had been castrated the year before. He wasn't sure that he wanted to admit that to Josh-if Josh still had his cock and balls.
When they got ready for sleep, Kelly watched as Josh stripped down to clean, snug, white, jockey briefs, then slipped into his twin bed. Josh hadn't been castrated. Kelly could see an unmistakable bulge in his crotch. Although small, it was evidence that-unlike Kelly-Josh was still a boy.
Kelly, wearing boxer shorts, turned his back to Josh, then got into the other bed. It wasn't that he was ashamed of being a eunuch. It's just that he thought that Josh might not understand. Boys who haven't been told about eunuchs never understand-not at first, anyway. He was afraid that Josh might laugh-or worse-think that he was some kind of freak. He couldn't stand that-not from Josh.
For the first time in almost a year Kelly regretted not having his boy parts. He'd never fooled around with another boy, but knew that boys sometimes did, comparing their cocks to see whose was the biggest-sometimes even whacking off together. If he'd still been a boy, he would have liked to have done that with Josh, but it was a year too late. He decided to keep it a secret from Josh that he was a eunuch Perhaps he could stuff a jock strap with a sock so he'd have a boy-like bulge in his pants, too.
Anyway, Josh had asked him a question: "How do you like it, Kelly?"
Thinking that he was talking about Santa Cruz, he answered, "I love this place. California is great."
That wasn't the question Josh was asking. He didn't care whether Kelly liked California or not. He knew that Kelly was a nullo-that he'd had both his cock and balls cut off. That's what he was dying to know about-what it was like to be a boy no longer, because, without a cock and balls, he wasn't a boy any longer-was he? Eunuchs or nullos-wasn't that what they called them? "No," he said, "that's not what I'm asking. What I want to know is what it's like to be a nullo? I heard that they did you last year. What's it like to have to sit down to pee-and stuff like that?"
Kelly felt his face flush. Josh knew. As clear as a bell he'd said that he knew. He hid his face in his pillow, trying not to cry. Back at home he had intact friends and even showered with the ones on his swim team. He was OK with that. They accepted him as he was-and he wasn't the only nullo in town. For all he knew, though, he might be the only nullo in Santa Cruz. It wasn't easy being the only nullo among a bunch of boys-especially boy who might not understand.
Looking over at his cousin, Josh thought, hell, he's crying just like a little girl. Nullos are different. He was curious, though. Perhaps, if he comforted him, Kelly would let him see it-and Josh wanted to see it. What did Kelly look like without a cock or balls? How did he pee? He walked over to Kelly's bed, sat down on it and began rubbing Kelly's back, saying, "You know, Kelly, being a eunuch is nothing to feel bad about. My mom says that eunuchs are much nicer than boys."
Uncovering his face, Kelly rolled over, looking up at his cousin. He was beautiful! It almost hurt to look at him. To Kelly, it was as if an angel had sat down on his bed. He wanted to reach up, pull his face down and kiss him. So, Josh already knew-but, did he really understand? Would he really accept him, knowing that he was a eunuch? "How did you know?" he asked.
.........................
As you can see, you lose some of the intimacy, but not a lot, and you can tell it from Josh's point of view at the same time. You could even tell what Josh's mother was thinking if you wished. For instance:
The next morning Josh said to his mom, "Mom, Kelly wants to go to the beach. Why don't we take him to Blue and White beach?"
"Oh, no, honey." she answered. I don't think that's a good idea-not with Kelly."
"Why not?" asked Josh. "It's a beautiful day."
"It might make Kelly uncomfortable-okay, sweetie." She had told Josh that Kelly had been nullified, but as usual he had little consideration for how others felt. Anna wished she could have him nullified, too. She was certain it would make him a better boy. He was already a terror, and he hadn't even reached puberty yet. God, she thought. What would he be like then? Although, as his only parent, she could have decided to have him nullified without his permission, she was afraid that it would ruin their relationship. She would just have to put up with his being a nasty boy.

This presented as an example of how the story could have been written
I'm not saying that it's better this way.
