I was sixteen when I found out not only am I an alien hybrid, but monsters called the Tai-Kok were getting ready to invade our world. Guess who gets to stop them? Me. How?

My uncle, the mad scientist, created a machine called the portal that instantaneously sends a test subject from one location to another by converting them into energy. His idea is to port me onto a Tai-Kok ship. All I have to do is leave a bomb, hit the retrieval button on my spiffy traveler’s belt and poof! I’m back on Earth before the Tai-Kok ship goes kaboom. Sounds simple, right?

Wrong. Uncle Ben doesn’t have a clue where I’ll actually appear on the ship. It could be the engine room, the crew quarters, or even the bridge. It’s like playing Russian roulette. The Tai-Kok don’t like surprises or uninvited guests.

To make things even more fun, I have an alien battle commander stuck in my head and I’m related to a powerful Coletti warlord. Yippee. The chances of me living to see eighteen aren’t good.

Undisciplined Catalyst is part of the Coletti Warlord Series by Gail Koger. Depending on the retailer or reading order list, it is sometimes labeled as Book 16.5 and other times appears later in the series (often listed as Book 19).

This discrepancy comes from how companion stories, novellas, and crossover entries are numbered across platforms. Regardless of numbering, Undisciplined Catalyst can be enjoyed on its own, especially by readers new to the series who want a fast, funny entry point into the Coletti universe.

📜 Excerpt

There's no easing into the chaos-Lexi's mission goes sideways almost instantly, and the result is equal parts danger and humor. Take a peek at this excerpt to see what I mean. GRM

"Give 'em hell." A wild look in his eyes, Uncle Ben tapped on the console.

The circles of light surrounded me, but this time it felt like a zillion fire ants were crawling over my body. Holy hell! Something had gone wrong! I appeared in midair and dropped like a rock. Smack! I slammed into someone, and my Glock went flying.

My eyes bugged. I was on the bridge of a futuristic warship, and the viewscreen showed one hell of a space battle going on. To make things even more fun, I was lying across the lap of a huge, muscle-bound male wearing black battle armor. Since he was sitting in the captain's chair, I was assuming he was the boss.

A very angry-looking boss. I blinked. Holy cow was he good-looking, if you were into the whole merciless predator thing. Huh? The red chains woven into his black warrior's braids matched the communication device on his left wrist. Who knew aliens accessorized and why did I care? I took a deep breath trying to control the panic streaking through me.

A low growl rumbled in his chest.

One look into his disturbingly hostile amber eyes and I knew I was in big trouble. I reached for my retrieval button.

His arms clamped around me painfully, and he spat a bunch of gobbledygook.

"Sorry, I don't speak that language," I replied mentally. Somehow, I knew he was psychic.

A harsh voice sounded in my head, "How did you get through our shields."

"Dunno. My uncle is the scientific genius, not me. I'm just the delivery girl."

"What do you deliver?"

Did I look stupid? The minute I told him bombs; he'd kill me. I pasted a friendly smile on my face. "Stuff. I'm Lexi and you are?"

"Battle Commander Kaelen. I serve Zarek the Coletti Overlord."

About Gail Koger

Author Gail Koger sitting on a park bench holding a small white dog on a leash. Outdoor setting with trees, grass, and sunlight in the background.

From Gail Koger:

I was a 9-1-1 dispatcher for the Glendale Police Department and to keep from going totally bonkers – I mean people have no idea what a real emergency is. Take this for example: I answered, “9-1-1 emergency, what’s your emergency?” And this hysterical woman yelled, “My bird is in a tree.” Sometimes I really couldn’t help myself, so I said, “Birds have a tendency to do that, ma’am.” The woman screeched, “No! You don’t understand. My pet parakeet is in the tree. I’ve just got to get him down.” Like I said, not a clue. “I’m sorry ma’am but we don’t get birds out of trees.” The woman then cried, “But… What about my husband? He’s up there, too.” See what I had to deal with? To keep from hitting myself repeatedly in the head with my phone I took up writing.
