I am currently writing the second book of my series and, as I was writing it, I have sometimes reread sections of my first book and come to the conclusion that it wasn't as good as I remembered. Because of my introverted nature, I've never been able to get anyone outside of my family to read my book and I was hoping to get an outside opinion of my writing style. I've attached a short sample of my first book here and am just interested in whether this is any good. I apologize for the format and lack of context, it was difficult to find a section that I could just slice out that wouldn't just be very confusing. For reference, Kes and Jack are both primary characters with Kes taking the role of the protagonist. Kes is thirteen, Jack is twenty-six, and Kes essentially is working as his assistant/apprentice. Here is the sample:
The conversation petered off as they approached Bawk’s house, a two-story Tudor-style building of brick and stone. A small balcony extended out over the lawn, which was adorned with flower gardens, each lovingly kept and abloom with roses, daffodils, and a dozen other flowers Kes couldn’t name.
“What a beautiful house,” Jack commented appreciatively. “This Mr. Bawk sure knows how to keep his living space in order.”
“Are we here to figure out where the Nekov Syndicate is keeping the Wall or to learn some tips about gardening?” Kes asked, annoyed.
“I don’t see why we can’t do both,” Jack said, shrugging. “It’s called multitasking and I’m quite adept at it.”
“It’s called easily distracted and you’re pretty good at that, too.” Kes stared at the front door. “So, how are we going to do this?”
“I imagine we knock. After that, anything could happen. Mr. Bawk could invite us in for a lovely high noon tea or he could jump out at us with a chainsaw. I know that second one seems unlikely, but it did happen to me once.”
“Really?”
“Indeed, it did. Although, it didn't take me especially long to subdue the man in question. Chainsaws don’t make very effective weaponry.”
On that note, Jack walked up to the front door, Kes on his heels. Raising his hand to the door, Jack rapped his knuckles against the polished wood and waited while the sound of footsteps approached from inside. The front door was pulled open by a tall, slightly overweight man in his mid-thirties. He had long black hair, coming down to his shoulders. He was good looking, in a plain sort of way.
“Hello?” the man asked, looking them over.
“Hello!” Jack said brightly. “I am Detective Jack Boundang. This is my associate Miss Kes Gatner. Would you happen to be Johnathon Bawk?”
Bawk licked his lips nervously. “I… yes, that’s me.”
“Excellent! I’m not going to beat around the bush, Mr. Bawk, because, while you do not look like a particularly busy man, I am very busy and simply don’t have time for things like small talk or subtlety. Are you or are you not part of the criminal organization known as the Nekov Syndicate?”
Bawk paled.
“I’m not a detective or anything, but that’s a yes, right?” Kes asked, nodding to Bawk’s expression.
“It would appear so,” Jack agreed.
“No!” Bawk said quickly. “No, I’m not part of the Nekov Syndicate! I mean, I was up until about three months ago… but then I quit! I swear, I’m not affiliated with them!”
“But you were,” Jack pointed out. “That’s the thing about being a part of stuff. No matter what you do afterwards, you will always once have been a part of said stuff.”
Kes nodded to Jack. “Can’t argue with that logic.”
Bawk swallowed. “Are you going to arrest me?”
“Oh, no, Mr. Bawk, rest easy,” Jack said, putting up a placating hand. “In fact, it’s quite the contrary. We need your help. We’ve come here, on our knees, to beg you for your assistance. Metaphorically speaking, of course. If I were to get on my knees right now, it would not only get my pants dirty, but my knees would start to hurt, and that wouldn’t be pleasant for anyone. My dry cleaner, for instance, would be highly irritated about the dirt on my pants.” Jack faltered for a moment. “I feel like I’ve gotten slightly sidetracked.”
Kes gave Jack a pointed look. “Easily distracted, like I said.”
“I do see your point, yes.” Jack looked at Bawk, who was quietly hyperventilating in the doorway. “Whatever the case, Mr. Bawk, we need to know some things, and you appear to be the perfect individual to talk to about them. May we come in? I believe we have a lot to discuss.”
Edit: I've gotten a lot of great positive feedback and constructive criticism here, thank you all very much! I'm hearing a lot of people say that the characters don't seem to have their own voice and tend to sound the same, along with a few comments about my use of adverbs, all of which I will attempt to take to heart. I will also be posting a request for beta readers in the appropriate subreddit, so if any of you are interested, I would genuinely appreciate your thoughts. Thank you all again!
