What’s The Photonic Effect About?

The Horizon is a science/exploratory vessel that was stuck out in deep space for a decade. Many adventures were had, new crew members were added, challenges faced. Think the U.S.S. Voyager. When they come home, they find that The Cluster (think Federation) has broken into Civil War. Members of the crew by family, origin planet, or perspective belong on both sides of the conflict.

But peace pretty much reigns on the ship (while strained) while they’re able to focus on their mission–an experimental drive. But their fleet commanders are dragging the Horizon into the conflict–and things start going wrong there.

On every level–levels that her captain, Demora Kim, probably wasn’t aware of. While Kim tries to keep her crew together, keep her command, and keep Horizon from having to fire a shot–some important allies the ship made while being stranded send a distress call.

If Kim can’t find a way to help–the destruction that follows could be devastating to their ally, the Horizon, and both sides of The Cluster’s War.

An Atypical Chen Novel

I’ve said this before—and Chen has talked about it frequently. Basically, Chen’s novels are only technically genre tomes. You have a love story, a story about fatherhood, relationships between siblings, family, etc.—and then he injects some SF or other genre elements into them.

This is straight-SF. Chen lets his geek run free here. Yes, there’s a lot of heart, he has a lot to say about romantic love, found family, loyalty, duty, and whatnot.

And it’s utterly fascinating—Chen puts us right in the middle of a saga. It almost feels like this should be book two or three of a series, and the reader has to play catch up with the history of the ship and its crew. The previous books* would be action-packed and full of great concepts. Getting thrown in like this was a great setup—we have to focus on this aftermath-type of story.

* I feel like I need to stress that these don’t exist. They’re purely theoretical previous books.

Why did I pick this up? Why did I keep reading?

Chen’s been an auto-pick-up for me for years. And I’ve never seen a reason to depart from that.
I kept on with this because this world, the characters, and the story were just so fascinating—there was no reason to walk away. I started here to list 2-3 things in particular that drove me on, but I couldn’t just pick a couple. I needed to know everything Chen wanted to tell me about this ship and crew. Period.

What does this book tell us about humanity?

One of the—if not the—most prominent things I picked up is trust. The need for trust, how people react when someone breaks that trust, and how hard it is to re-establish it. But for those who can rebuild—or have the grace to keep it—how great a safety it is. And, sadly, the damage that can be done when the wrong people are trusted.

In this book, that goes beyond humanity to other races, too.

There’s also a great deal to say about loyalty–and combating loyalties. The Horizon‘s crew has a great deal of loyalty to each other (tested by some trust issues), but they also have loyalties to their families, loved ones, planets, their government, and so on.

Loyalty and trust are both tested and broken on several levels for every character, and the question is–what do you (and the rest of your crew) do in the face of a common challenge when those don’t remain?

So, what did I think about The Photonic Effect?

I don’t think this is Chen’s best work. But I did enjoy watching him cut loose on a Space Opera.

I loved, loved, loved the way that we’re dropped into this thing mid-story–or mid-arc–and had to catch up. Getting to figure out what’s going on while guessing/assuming details of what came before was an extra layer of enjoyment.

There are two primary characters–the Captain and Chief Engineer (I think that’s his title, or maybe I’m just assigning that to him. He’s a Scott/LaForge/Lamarr-type character). I would read a multi-part series with these two–or with either of them. Watching them navigate their way through the twisty plot and strange events is more than enough for me.

I was on the edge of my seat throughout the book, while filling in the backstory all the while; the cast of characters was outstanding, with many competing motivations throughout (all of them believable); the universe this was set in could be the framework for a huge series, and it was nice to be introduced to. It missed the je ne sais quoi to make me rave about–but I can’t imagine someone picking it up and not coming away satisfied.
